1.49a causes gcc-2.95.3+ to fail to build

[Mike Castle]

Installed bison 1.49a.

Rebuilt gcc-2.95.3+ (ie, fairly recent stuff off the cvs 2_95-branch).

When building gcc, I get the following error:

make[2]: Entering directory `/usr/src/gcc/gcc-2.95.3-build/i386-linux/libobjc'
/usr/src/gcc/gcc-2.95.3-build/gcc/xgcc -B/usr/src/gcc/gcc-2.95.3-build/gcc/

make[2]: *** [linking.o] Error 1
make[2]: Leaving directory
`/usr/src/gcc/gcc-2.95.3-build/i386-linux/libobjc'

Reverting to bison-1.35 allows gcc to build correctly (rebuilding from
scratch each time).

Usually I'm suspicious of signal 11 errors, but this one was reproducible
and went away with the change, so....

Cheers,
