into libc. This reduces the size of every dynamically linked
executable by 248 bytes, and it reduces the size of static executables
by a lesser amount. It also eliminates some global namespace
pollution.
With this change in place, the source for dlfcn.h should probably
be moved to "/usr/src/include". I'll save that for another day.
Compatibility note: Programs which use dlopen, if compiled on
systems with this change, will not run on systems with a libc from
prior to this change. Very few programs use dlopen, so I think
that is OK.
This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.
Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.
specified in the top level Makefiles.
Previously I missed dozens of Makefiles that skip the install after
using `cmp -s' to decide that the install isn't necessary.
1) Do dependencies.
2) Install all appropriate links to manual pages.
3) Install header file in `beforeinstall' like all the rest.
4) Install header file only if changed.
5) Install object files only if changed.

It will be easiest way now to make national chars available
for all ctype-oriented programs at once by simple:
setenv LANG Your_National_Charset
Default case (without "LANG" environment
variable) will be fully ANSI compatible (got "C" locale).
If "LANG" variable present, extention becomes active.
Effect of this extention is great: in one time all ctype
oriented programs can accept/print national characters
without any touching source/binary code, it is big win, IMHO.
This method is fully compatible with ISO8859-* and russian koi8-r
too (in general -- with all 8-bit character sets). I think
it is very useful.
I got this idea from Xenix locale implementation.
This extention is even never compiled in, unless you set
setenv STARTUP_LOCALE
before rebuilding crt0.c or corresponding variable in /etc/make.conf
<machine/profile.h>. The old version was writing an incomplete
header without the profrate field that is necessary to handle the
current faster profiling clock. The counters that are where the
the profrate should be are usually 0 and gprof converts a profrate
of 0 to hz so the old version gave times too large by a factor of
profhz/hz = 10.24.
This fixes the problems Warner's having with ctors not being called
again with the latest round of ld changes and updates the file-names to what
Paul is using now.
The name change will not affect anything as we are not (yet) using it.
