i know this file, but without an Compiler and without any knowledge about cygwin, is this file not realy helpfull.
its my first time to recompile an module under windows. i'am a starter in Perl, so it's not so easy for me!
with google, i found many people with the same problem, but no solution for my problem.
I don't use windows that much these days, however this blog post discusses compiling the jpeg library using MinGW (the post linked to above will tell you how to setup MinGW) on a windows platform.
