According to Nick Cremelie:
../../xgpc -B../../ --automake -c -DGPC -Wall -Wpointer-arith -Wmissing-prototy pes -Wmissing-declarations -g -O2 -I. -I../.. -I/backup/gnu/gcc-2.8.1/p/rts/.. /.. -I/backup/gnu/gcc-2.8.1/p/rts/../../config rts-base.p rts-base.p:56: warning: no previous prototype for `__init_Rts_base' xgpc: Internal compiler error: program gpc1 got fatal signal 6
Please try to compile rts-base.p manually, giving the additional option `-dY'. This will dump the source to `stderr' thus showing us after which line the error occured.
After that, please retry with `-dy' instead of `-dY' which will dump - a lot of - parser debugging information to `stderr'.
In both cases, please post the last, say, 10 lines of the output to this list.
Thank you for reporting the problem,
Peter
