[Numpy-discussion] Setting C and linker flags for Windows build

Hi, I am very sorry - I feel I should know this, or be able to work it out, but is there a way of setting the flags to the C compiler and the linker, for the Numpy build, on Windows? I'm trying to set the flags for a build with Windows mingw-w64 - but I believe Numpy is ignoring $env:LDFLAGS, $env:CFLAGS and $env:OPT - and I can't see any way of setting these options from the command line. Am I missing something? Cheers, Matthew
