MSVs have not implemented va_copy. remove va_copy at MSVC environment.
It will malloc buffer each time.

... but only a 257-byte buffer as dscho pointed out.

In many places that do not have va_copy, a simple assignment works.  And
va_end is almost always a no-op. So what about

#ifndef va_copy
#define va_copy(dst, src)       ((dst) = (src))
#endif

if it works on MSVC?

According to http://stackoverflow.com/questions/558223/vacopy-porting-to-visual-c
that should work.
