Gmake is slow under cygwin

[Marcus A Martin]

I am writting a build environment for a large progect. We use gmake to
compile or code on linux, SGI and windows 2k (via cygwin). While the build
environment can do all the preprocessing before a build very quickly on the
unix boxes, it can take up to 2 minutes on a windows box. This is a serious
diffence.

To give you an idea of what might be causing the problem, here is what our
make system does. When you execute make, it calls a find command to find all
the files called localdefs.mk. Each localdefs.mk file contains a list of
source files, defines the target as a library or an application, identifies
any exported headers, and then calls a make template. The make template
contains the rules on how everything is built. All of the localdefs.mk files
are processed in memory, then make begins the compilation of any file that
needs to be built.

The initial find takes 2-5 seconds but each localdefs.mk file takes 1-2
seconds to process in memory under a cygwin/windows box.  With about 150
libraries and applications, the time really adds up. Do you have any ideas
as to how I can accelerate the windows performance?

Thanks for the help,

Marcus
