egcs-2.93.06 sparc-sun-sunos4.1.4 bootstrap fails with --enable-c-cpplib

[Kaveh R. Ghazi]

	When I bootstrap "egcs-2.93.06 19990211" on sparc-sun-sunos4.1.4
using --enable-c-cpplib, cc for stage1 and BOOT_CFLAGS = "-g -O2
-D__USE_FIXED_PROTOTYPES__ -pipe", I get this crash in stage2:


 > ./genrecog ./config/sparc/sparc.md > tmp-recog.c
 > /bin/sh: 13472 Bus error - core dumped
 > make[2]: *** [s-recog] Error 138


	Here is the backtrace from gdb:
