Hi, when trying to build a DLL (I think it'd be the same thing with an EXE though) with the -static-libgcc flag using the mingw-w64 cross-compiler in the Fedora 17 repository, I ran into symbol conflicts between libgcc_eh.a and libgcc_s.a: there are errors about multiple definitions of several "_Unwind_*" symbols. Unfortunately, the code uses exceptions, so -fno-exceptions is not an option.
http://tdm-gcc.tdragon.net/development says that TDM-GCC (maintainer CCed) has a local patch for what appears to be this same issue: > Includes a patch which reintegrates the code from libgcc_eh.a into libgcc.a > and the libgcc DLL. As long as the shared memory region is used to handle > exceptions, this library is unnecessary, and it causes multiple definition > errors for the symbols in it because it hasn't been added to binutils' > exception libraries yet. Therefore I am asking whether we can get that fix (or some other fix for this bug): 1. into the Fedora mingw64-gcc packaging and 2. into upstream GCC?
