------- Comment #1 from pinskia at gcc dot gnu dot org 2007-01-05 05:12 ------- First libmudflap really cannot be supported on cygwin. Second your patch for libgomp should be sent to the gcc-patches@ list. Third you are incorrect in saying mmap does not work because it does for so many other people, it might mean you have an older version of cygwin.dll installed.
Fourth to check the compiler/libraries, just do "make -k check". in the build directory. Note the -k. This is documented in http://gcc.gnu.org/install/test.html already. Also building in the source directory is not supported that much. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=30342
