Thanks for your reply. The problem is we were not using pure llvmgcc(otherwise we should be able to use gcc4.6+dragonegg, I think), and a lot changes were made to llvmgcc for our own purpose. If we switch our compiler to clang, there will be a lot of manual patch work... Maybe the MinGW patch for gcc4.4 can be useful for me.</blockquote>
<div><br>GCC 4.2 is unusable for Windows x64. 4.3 is buggy, 4.4 is buggy but workable. I think you'll have better luck using a standard released compiler (implying manual patchwork, I hope you mean to your codebase, not Clang's).<br>
<br>MinGW-w64 + GCC's older than 4.4 is a no-go. Sorry.<br><br>Ruben<br><br>

MinGW-w64 only started existing around GCC 4.3, with a working implementation at GCC 4.4 (with lots of local patches required) and a vanilla (unpatched) implementation at GCC 4.5+. I think you're currently out of luck here. Why not try Clang itself (if you don't need fortran or any other non-C family language of course)?<br>
