The attached patch adds a definition for the keyword
WINADVAPI and ultimately defines it as
Even though WINADVAPI is not used in any current
MinGW win32api header, some 3rd party headers do use
it and fail compiling with MinGW when WINADVAPI is
not defined somehow.
Obviously winbase.h is the canonical place for this
#define. The define itself is a trivial copy of the
WINBASEAPI define that's already in winbase.h.
