Mon Feb 24 17:08:01 1992 K. Richard Pixley (rich@rtl.cygnus.com) Tue Mar 10 21:49:18 1992 K. Richard Pixley (rich@mars.cygnus.com)
* configure: use relative paths for configure and srcdir whenever
possible.
Tue Mar 10 18:01:55 1992 Per Bothner (bothner@cygnus.com)
* Makefile.in: Fix libg++ rule to check for gcc directory
before using gcc/gcc. Also pass XTRAFLAGS.
Thu Mar 5 21:45:07 1992 K. Richard Pixley (rich@sendai)
* Makefile.in: added stmp-files so that directories aren't polled
when they are already built.
* configure.texi: fixed a node pointer problem.
Thu Mar 5 12:05:58 1992 Stu Grossman (grossman at cygnus.com)
* config.sub configure.in config/.Sanitize config/mh-irix4
gdb/.Sanitize gdb/configure.in gdb/mips-tdep.c gdb/mipsread.c
gdb/procfs.c gdb/signame.h gdb/tm-irix3.h gdb/tm-mips.h
gdb/xm-irix4.h gdb/config/.Sanitize gdb/config/mt-irix3
gdb/config/mh-irix4 texinfo/configure.in: Port to SGI Irix-4.x.
Wed Mar 4 02:57:46 1992 K. Richard Pixley (rich@rtl.cygnus.com)
* configure: -recurring becomes -silent. corrected help message
for -site= option.
* Makefile.in: mkdir $(exec_prefix) and $(tooldir).
Tue Mar 3 14:51:21 1992 K. Richard Pixley (rich@rtl.cygnus.com)
* configure: when building Makefile for crosses, replace
tooldir and program_prefix. default srcdir from location of
config.sub. remove "for host in hosts" and "for target in
targets" loops.
Wed Feb 26 19:48:25 1992 K. Richard Pixley (rich@rtl.cygnus.com)
* Makefile.in: Do not pass bindir or mandir to cvs.
Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
* Makefile.in, configure.in: removed traces of namesubdir,
-subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
copyrights to '92, changed some from Cygnus to FSF.
* configure.texi: remove most references to multiple hosts,
multiple targets, subdirs, etc.
* configure.man: removed rcsid. reference config.sub not
config.subr.
* Makefile.in: mkdir $(infodir) on install-info. * Makefile.in: mkdir $(infodir) on install-info.
