Compiling libstdc++-2.90.7 on Solaris 7

[Viraj Alankar <valankar at cse dot fau dot edu>]

Hello,

	We are having a problem compiling libstc++-2.90.7 on Solaris 7
with gcc 2.95.2:

c++ -DHAVE_CONFIG_H -I. -I../../libstdc++-2.90.7/src -I.. -nostdinc++
-I../../libstdc++-2.90.7/config/solaris -I../../libstdc++-2.90.7
-I../../libstdc++-2.90.7/stl -I../../libstdc++-2.90.7/libio -D_GNU_SOURCE
-fno-implicit-templates -Wall -Wno-format -W -Wwrite-strings -Winline
-Werror -g -fno-honor-std -c  -fPIC -DPIC
../../libstdc++-2.90.7/src/locale.cc -o .libs/locale.lo

gmake[1]: Leaving directory `/home/home4/valankar/gcc/bld-libstdc++'
gmake: *** [all-recursive-am] Error 2

	I noticed mention of this on the mailing list, and tried the patch
to config/solaris/bits/ctype_base.h changing:

typedef long*               __to_type;

to

typedef int*               __to_type;

	After this change I was able to compile the library successfully.
However, when I tried using the lib my executables would core dump:

uname -a

	Anyone know what may be wrong? Thanks for any help.
