Hello,
Since r177358, a host executable gengtype is built so that plugins can
use the GTY markers.
Even for the host, gengtype is a GENERATOR_FILE, but since the build-%
rule doesn't apply to host objects, gengtype was being built without
it. So when I removed coretypes.h from double-int.h, my build failed.
Fixed by adding -DGENERATOR_FILE explicitly to the host gengtype*.o objects.
Bootstrapped on powerpc64-unknown-linux-gnu. OK for trunk?
Ciao!
Steven
* Makefile.in (gengtype-lex.o, gengtype-parse.o, gengtype-state.o,
gengtype.o): Add -DGENERATOR_FILE manually for host gengtype objects.
