dnl CF_CONST_X_STRING version: 4 updated: 2020/03/10 18:53:47
|
|
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 -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
