In mingw-w64-headers/configure.ac is missing case for the crtdll. Usage of crtdll as CRT library is treated with zero value in __MSVCRT_VERSION__ and setting additional __CRTDLL__ macro. Setting of __CRTDLL__ is needed also to mimic compatibility with gcc, which can be configure to target crtdll.dll by default in which case it predefines __CRTDLL__ macro. --- mingw-w64-headers/configure.ac | 3 +++ mingw-w64-headers/crt/_mingw.h.in | 4 ++++ 2 files changed, 7 insertions(+)
