- Subject: Using GCC 2.95 as a bootstrap compiler
Aparently current mainline triggers a bug in GCC 2.95 or we might be
encountering undefined behavior in our PCH-related code?
In any case, some ten days ago (rough estimate) mainline stopped building
both with stock GCC 2.95.3 and the FreeBSD system compiler (GCC 2.95.4) on
i386-unknown-freebsd4.8:
/sw/gcc-2.95.3/bin/gcc -g -DIN_GCC -W -Wall -Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes -pedantic -Wno-long-long -DHAVE_CONFIG_H -DGENERATOR_FILE -o gengtype \
gengtype.o gengtype-lex.o gengtype-yacc.o ../libiberty/libiberty.a
./gengtype
