This topic came up about a year ago on this list: http://sources.redhat.com/ml/cygwin-apps/2000-07/msg00039.html
and I've recently raised it again on mingw lists. Looking at cygwin's spec file it says: *cpp_cpu_default: %(cpp_686) To me that means that, unless user overrides with command line -march or -mcpu option, code is tuned for i686. To get that into the specs file, one has to either configure gcc so that TARGET_CPU_DEFAULT=3 (=pentium) or pass that define to make when building gcc. That interpretion is different from the conclusion that was posted in the message pointed to above, which says that cygwin-produced code will run on any i[35467]86 arch. I'm not talking about the platform triplet moniker -- that I realise is just a name. I'm asking: Has anyone complained that cygwin-built apps fail on i386 but not on i686?
