See the "begging for binaries" thread. I think the approach that finally
worked was this (having fixed the unfortunate typo I originally wrote):
Find the gcc specs file. If gcc.exe is %mingwpath%\bin\gcc.exe, and the
version is %mingwversion%, then the specs file should be
$mingwpath%\lib\gcc\%mingwversion%\specs . Change "-lmsvcrt" to
"-lmsvcr71".
Now, edit scipy_distutils/mingw32ccompiler.py at around line 102 or so:
"""
# no additional libraries needed
self.dll_libraries=[]
return
"""
to
"""
# no additional libraries needed
self.dll_libraries=['msvcr71']
return
"""
