I think that I might need to explain my self better.  All of these 
header files *do* exist on my system, but xmkmf/makedepend are 
looking in directories which only existed in the previous version of 
cygwin.  Looking at the error, makedepend looked in the following 
directories for these headers:

 /usr/X11R6.4/include/
* I have this dir, but it only contains headers for X

 /include/
* This does not exist in cygwin 1.1.1

 /usr/local/lib/gcc-include/
* This does not exist in cygwin 1.1.1

 E:/usr/H-i386-cygwin32/i386-cygwin32/include/
* This does not exist in 1.1.1, and I do not have an E: drive

 E:/usr/H-i386-cygwin32/lib/gcc-lib/i586-cygwin32/egcs-2.91.57/inc 
lude/
* This does not exist in 1.1.1, I do not have an E: drive, and I do not 
   have egcs installed on my system.  I compile with gcc 2.95.2

When I asked where does xmkmf get its info from, what I should 
have said is:  Why is xmkmf searching these directories for 
headers.  On Cygwin 1.1.1 all of the headers exist in the following 
directory:

/usr/i686-pc-cygwin/include

This is the way Cygwin 1.1.1 installed itself on my system.  I have 
not modified it at all.  I have successfully built many other binaries 
which do not use xmkmf, which leads me to believe that xmkmf is 
reading an old file somewhere which is telling it to look in these old 
B20 style directories for the header files.

As a quick and dirty fix for this I mounted 
/usr/i686-pc-cygwin/include as /include because for what ever 
reason xmkmf was looking in /include for the headers contained in
/usr/i686-pc-cygwin/include.  When I did this xmkmf -a  
successfully completed.  Then when I tried to make the binary, 
make died with undefined reference to `_ctype_' errors which 
referred to libXm.a.  This shows that even with the proper headers 
there is still a problem with libXm.a.  So to sum up

1. How do I get xmkmf/makedepend to look in the proper 
directories for the needed headers?

2. Does libXm.a need to be rebuilt for cygwin 1.1.1?

Thanks Again,
