Fri Nov 13 00:15:08 1998 Geoffrey Noer <noer@cygnus.com>
Changes to account for name change from cygwin32 to cygwin and
clean up Win32-related ifdefs.
* configure.tgt: check for cygwin* instead of cygwin32.
New cygwin gdb_target variable loses the "32".
* configure.host: check for cygwin* instead of cygwin32.
New cygwin gdb_host variable loses the "32".
* configure.in: test __CYGWIN__ instead of __CYGWIN32__,
rename gdb_cv_os_cygwin32 variable to drop the "32". Call
AM_EXEEXT instead of AC_EXEEXT since that isn't in a released
autoconf yet.
* configure: regenerate.
* main.c: drop "32" from cygwin_ funcs, include sys/cygwin.h
where
cygwin path conv protos live, instead of adding a proto here
for
them here.
* {main.c, ser-tcp.c, ser-unix.c, top.c}: check __CYGWIN__
instead of __CYGWIN32__.
* source.c: thoughout, check _WIN32 instead of WIN32.
* config/i386/cygwin32.mh: delete.
* config/i386/cygwin.mh: new file, was cygwin32.mh.
* config/i386/cygwin32.mt: delete.
* config/i386/cygwin.mt: new file, was cygwin32.mt.
* config/i386/tm-cygwin32.h: delete.
* config/i386/tm-cygwin.h: new file, was tm-cygwin32.h.
* config/i386/xm-cygwin32.h: delete.
* config/i386/xm-cygwin.h: new file, was xm-cygwin32.h.
* config/i386/xm-windows.h: #include xm-cygwin.h now.
* config/powerpc/cygwin32.mh: delete.
* config/powerpc/cygwin.mh: new file, was cygwin32.mh.
* config/powerpc/cygwin32.mt: delete.
* config/powerpc/cygwin.mt: new file, was cygwin32.mt.
* config/powerpc/tm-cygwin32.h: delete.
* config/powerpc/tm-cygwin.h: new file, was tm-cygwin32.h.
* config/powerpc/xm-cygwin32.h: delete.
* config/powerpc/xm-cygwin.h: new file, was xm-cygwin32.h.
* rdi-share/aclocal.m4: regenerate with aclocal.
* rdi-share/configure: regenerate with autoconf.
* rdi-share/{host.h, hostchan.c, hostchan.h, serdrv.c,
* serpardr.c,
unixcomm.c}: check __CYGWIN__ instead of __CYGWIN32__.
