problem compiling gcc 2.9.5

[Bryan Weston]

I am trying to compile gcc 2.9.5, on Solaris 2.6 and I get the following
error.


bryanw@bluemoon: /tmp/a/gcc-2.95
78 % make bootstrap
gnumake[1]: Entering directory `/tmp/a/gcc-2.95/libiberty'
test x"yes" != xyes || \
  gcc -c -DHAVE_CONFIG_H -g -I. -I./../include  `case "-g -g -O2
-fno-implicit-templates" in *-fpic* ) echo -fpic ;; * ) echo -fPIC ;;
esac` vsprintf.c -o pic/vsprintf.o
vsprintf.c: In function `vsprintf':
vsprintf.c:47: `_IOSTRG' undeclared (first use in this function)
vsprintf.c:47: (Each undeclared identifier is reported only once
vsprintf.c:47: for each function it appears in.)
gnumake[1]: *** [vsprintf.o] Error 1
gnumake[1]: Leaving directory `/tmp/a/gcc-2.95/libiberty'
gnumake: *** [all-libiberty] Error 2
 

I looked everywhere but could not find a definition for _IOSTRG. I am
compiling with egcs 1.1.2, but also tried with gcc 2.8.1.
