Before I try your suggestions, another question: It seems like setting BOOT_CFLAGS to include "-m64" should do what I want. The Makefile says: # BOOT_CFLAGS is the value of CFLAGS to pass to the stage2, stage3 and stage4 # bootstrap compilations. If I understand this correctly, this would cause gcc from the later stages to be called with -m64, so that they would, when building the compiler, produce 64-bit objects and be able to link against my 64-bit libgmp and libmpfr. Is this right? Thanks. -David -- David Eisner http://cradle.brokenglass.com
