Re: Problem linking in pthread librarry.... (Newbie)

[Ed Hume <hume@hume.com>]

I believe the __imp__ prefix comes from the functions being declared
as DLL imported/exported symbols.  So I think you need to go review
the header files, and fix up some macros in your makefile so that the
__declspec(dllexport) macros are not used.  (For example, have your
definition of PTW_EXTERN)
