vcbuild/builddmd.bat is not working with MSVS2010 1. it can't create libraries, 'cause msvc link is command-line incompatible with dmc link 2. it can't compile scanmscoff.c (invalid c compiler flags) 3. it can't compile mscoffobj.c (invalid c compiler flags) 4. and finally, after hacking aroung previous bugs it can't link dmd.exe
There's no longer a builddmd.bat, closing? You can build a 64-bit dmd.exe with win64.mak if that's what you were after.
