I am quite new to clapack and have experienced a problem compiling using VC Express. Clapack compiles without problems as long as I do not #include <windows.h>. When I do, however, conflicts with a few lines in f2c.h and clapack.h occur. When I examine the specific lines in these two headers where redefinition or syntax problems occur, I can't see anything wrong. I am certain others must have experienced these problems too. How do I include windows.h and not run into conflicts?
