I am trying to compile gcc 3.4.1 on SFU 3.5. The build ends abruptly, after many warnings, with the error : ../../libiberty/fibheap.c:285: error: `LONG_MIN' undeclared (first use in this function) I am new to GNU style building but was able to figure out that config.status is not updating config.h in libiberty with the proper defines so include files are correctly included. The command I used to build were: md objs cd objs ../configure gmake bootstrap I have automake 1.8.1, autoconf 2.59.2 and gmake 3.80.1 installed. After I get beyond this hurdle I will apply the Interix gcc 3.3 patches. Any hints would be much appreciated. Thanks, Barry
