dnl all of those were combined into a page of useful graphics characters.
|
|
dnl
|
|
dnl So far, so good.
|
|
dnl
|
|
dnl However, while they are useful, there are other considerations. CJK
|
|
dnl is (because of poor device resolution) often rendered as double-width
|
|
dnl characters. So... for these generally-useful characters, what should
|
|
dnl be the width (to make them consistent with adjacent characters)?
|
|
dnl
|
|
dnl The obvious choice would have been to make this locale-dependent, and use
|
|
dnl wcwidth() to tell applications what the actual width is. That was too
|
|
dnl obvious. Instead, we have a slew of "ambiguous-width" characters.
|
|
dnl See for example
|
|
dnl http://www.unicode.org/reports/tr11/tr11-29.html
|
|
dnl http://www.cl.cam.ac.uk/~mgk25/ucs/scw-proposal.html
|
|
dnl
|
|
dnl The EastAsianWidth-6.2.0.txt file from the Unicode organization lists
|
|
dnl more than 22,000 characters, with 1281 of those as ambiguous-width. For
|
|
dnl instance, it lists half (44/96) of the Latin-1 characters as
|
|
dnl ambiguous-width. Also, all of the box-characters at 0x2500 are ambiguous.
|
|
dnl
|
|
dnl What this means for the implementor is that on some systems wcwidth() can
|
|
dnl give bad advice. On Solaris, some of the ambiguous widths are returned as
|
|
dnl 1 (the Latin-1 characters), while others are returned as 2 (line-drawing
|
|
dnl characters). These do not necessarily match the behavior of the terminal
|
|
dnl emulator. xterm, for instance, does an optional startup check to find if
|
|
dnl this problem (or similar) exists with the system's locale tables, rejecting
|
|
dnl them if they are too unreliable.

|
|
dnl -----------------
|
|
dnl The X11R4-X11R6 Xt specification uses an ambiguous String type for most
|
|
dnl character-strings.
|
|
dnl
|
|
dnl It is ambiguous because the specification accommodated the pre-ANSI
|
|
dnl compilers bundled by more than one vendor in lieu of providing a standard C
|
|
dnl compiler other than by costly add-ons. Because of this, the specification
|
|
dnl did not take into account the use of const for telling the compiler that
|
|
dnl string literals would be in readonly memory.
|
|
dnl
|
|
dnl As a workaround, one could (starting with X11R5) define XTSTRINGDEFINES, to
|
|
dnl let the compiler decide how to represent Xt's strings which were #define'd.
|
|
dnl That does not solve the problem of using the block of Xt's strings which
|
|
dnl are compiled into the library (and is less efficient than one might want).
|
|
dnl
|
|
dnl Xt specification 7 introduces the _CONST_X_STRING symbol which is used both
|
|
dnl when compiling the library and compiling using the library, to tell the
|
|
dnl compiler that String is const.

dnl ---------------

dnl Check if the compiler supports useful warning options. There's a few that

|
dnl we don't use, simply because they're too noisy:
|
|
dnl
|
|
dnl -Wconversion (useful in older versions of gcc, but not in gcc 2.7.x)
|
|
dnl -Winline (usually not worthwhile)
|
|
dnl -Wredundant-decls (system headers make this too noisy)
|
|
dnl -Wtraditional (combines too many unrelated messages, only a few useful)
|
|
dnl -Wwrite-strings (too noisy, but should review occasionally). This
|
|
dnl is enabled for ncurses using "--enable-const".
|
|
dnl -pedantic
|
|
dnl
|
|
dnl Parameter:
|
|
dnl $1 is an optional list of gcc warning flags that a particular

|
dnl application might want to use, e.g., "no-unused" for
|
|
dnl -Wno-unused

dnl Option to allow user to override automatic configuration of manpage format.
|
|
dnl There are several special cases:
|
|
dnl
|
|
dnl gzip - man checks for, can display gzip'd files
|
|
dnl compress - man checks for, can display compressed files
|
|
dnl BSDI - files in the cat-directories are suffixed ".0"
|
|
dnl formatted - installer should format (put files in cat-directory)
|
|
dnl catonly - installer should only format, e.g., for a turnkey system.
|
|
dnl
|
|
dnl There are other configurations which this macro does not test, e.g., HPUX's
|
|
dnl compressed manpages (but uncompressed manpages are fine, and HPUX's naming
|
|
dnl convention would not match our use).

dnl
|
|
dnl Notes:
|
|
dnl a) ${LOCAL_LDFLAGS} is used to link executables that will run within
|
|
dnl the build-tree, i.e., by making use of the libraries that are compiled in
|
|
dnl $rel_builddir/lib We avoid compiling-in a $rel_builddir/lib path for the
|
|
dnl shared library since that can lead to unexpected results at runtime.
|
|
dnl b) ${LOCAL_LDFLAGS2} has the same intention but assumes that the shared
|
|
dnl libraries are compiled in ../../lib
|
|
dnl
|
|
dnl The variable 'cf_cv_do_symlinks' is used to control whether we configure
|
|
dnl to install symbolic links to the rel/abi versions of shared libraries.
|
|
dnl
|
|
dnl The variable 'cf_cv_shlib_version' controls whether we use the rel or abi
|
|
dnl version when making symbolic links.
|
|
dnl
|
|
dnl The variable 'cf_cv_shlib_version_infix' controls whether shared library
|
|
dnl version numbers are infix (ex: libncurses.<ver>.dylib) or postfix
|
|
dnl (ex: libncurses.so.<ver>).
|
|
dnl
|
|
dnl Some loaders leave 'so_locations' lying around. It's nice to clean up.
