What's going on here? It links fine with the MIPS C compiler (2.11). We have been compiling our production code -O3 for years because we get significant performance improvements. Who can I complain to? Is engineering listening? And what about maintaining compatibility with MIPS? This is not a good sign. Greg Couch gregc@cgl.ucsf.edu
