Yes, you did need CygIPC.  However, you now either have to rebuild 
XFree86 with the X Shared Memory Extension or you have to install the 
few files thare changed when XSHM is enabled.  The KDE on Cygwin project 
distributes these changed files and they have instructions on how to 
install them.  You need the KDE-X package from the way bottom of this page:

The KDE on Cygwin folks have the answer for undefined references to shmat:

Yes, you could rebuild Cygwin/XFree86 with shared memory support, but I 
recommend just installing the KDE on Cygwin package that provides the 
modified files.

Not sure.  I am pretty sure that imlib and GTK+ both work but that they 
have to be static libraries, to a degree.  At least, there was not an 
optimal solution for building GTK+ with a shared library the last time I 
checked into it.

No problems with FAT32.  Don't believe everything that you read.

Hope that helps.

P.S. I am cheering for Solectron, booh Flextronics  :)  Just kidding.
