output_lang_identify, ASM_IDENTIFY_.. AIX 19980517-build failed

[Yotam Medini <yotam at avanticorp dot com>]

After failing to build egcs-19980517 using native compiler, I built
gcc-2.8.1 and used it for egcs build. By the way --enable-gcc is not
enough, I had to add CC=gcc environment for configure.

Now I get:

 gcc -DIN_GCC -g -DHAVE_CONFIG_H -DHAIFA -o cc1 c-parse.o c-lang.o

I guess the inactivating '#if 0' in  toplev.c  for
   output_lang_identify(FILE*)
should be synchronized with  defaults.h  macros:
   ASM_IDENTIFY_GCC, ASM_IDENTIFY_LANGUAGE
