How about not #define'ing rename() etc in port.h in the first place?
We could put
#ifdef WIN32
#define rename(x) pgrename(x)
#endif
into those very few .c files that need it. (I'm assuming that
forgetting to include this in a file that calls rename() will yield an
obvious build failure on Windows --- if not then the idea is no good.)
