-std=c89 is too strict: IIRC it will disable anonymous unions which is
supported by both gcc and msvc and often used in headers.  A -std=msvc
option would be nice though. 

Even better would be c99 support in msvc. Unfortunately MS seems little
very excited about C99, but it is commited to C++0x, which brings some
C99 features [1][2].
