------- Comment #6 from dannysmith at users dot sourceforge dot net 2008-08-01 04:34 ------- This kind of path '--prefix=/c/_GccBuilds/gcc-4.3.1-install/mingw-32-i686' may be understood by your shell, but won't be found by the xgcc driver or cc1.exe which are native windows apps. Search the mingw site for a build script that will work with the msys shell.
