To compile the files for Win95/Win98/WinNT set the CPATH variable to where you have your Visual C++ compiler. Eg. SET CPATH=C:\DEVSTUDIO\VC Then copy the Makefile.win32 to the makefiles and use nmake. Other notes of interest : -You need the LIBTIFF package to declare the tiffio.h, I found it at ftp://ftp.sgi.com/graphics/tiff. (tiff-v3*.gz). (Not functional yet.)
