OK, here's something like a test case. Since a couple of my previous 
attempts to post a reply with a zip file attachment were unsuccessful, 
I've put the test case here:
http://debian.fmi.uni-sofia.bg/~angel/test_case_make_3.80.zip

The result I get when running (the cygwin version of) make on my 
system is:
Source/File1.h Source/File2.h h

And the expected result is:
Source/File1.h Source/File2.h

Result of running 'make --version':
GNU Make 3.80

It is a very strange problem. A couple of weeks ago I started a thread 
about the exact same problem on the make-w32 mailing list, assuming it 
had something to do with long file names. The thread is located here:

http://lists.gnu.org/archive/html/make-w32/2005-07/msg00011.html

As one can see, this problem has been fixed. Unfortunately, no newer 
version of make has been release so far, except for betas, the latest 
one being is 3.81beta3. The source code of the windows version of 
3.81beta3 is available at
ftp://alpha.gnu.org/gnu/make/
