Maybe you could offer a few more details; I just tried

--- Comment #16 from howarth at nitro dot med dot uc dot edu 2006-11-03 03:36 --- After patching configure.ac and regenerating configure in zlib with... aclocal -I ../config autoreconf -I ../config I find that I don't get a zlib subdirectory in the powerpc-apple-darwin8 build directory anymore. I am assuming that the patch has freed the gcc build to use the system zlib instead. Interestingly, if I compare what I see on i386 linux, I don't see a zlib build subdirectory created for a stock gcc 4.2 build there. However if I look at a build on x86_64, I see a zlib build subdirectory which suggests I may have fixed a bug in the build of zlib on multilib systems with this zlib patch. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=26814

I just want cc1 to be compiled with -m64 so that it can allocate 2.4GB of storage when it's compiling some computer-generated C files.
