make in Cygwin fails on compiling callproc.c

Done the following:

-- got a fresh new machine preinstalled wtih Windows XP Home edition, no Visual 
C or any development tools
-- installed the newest Cygwin I could get on www
-- in rxvt (a Cygwin console window) unpacked emacs-21.4a.tar.gz
-- mounted the directory with mount -t
-- cd emacs-21.4/nt; ./configure.bat; make

Make fails on file src/callproc.c with conflicting types for egetenv. I look 
into the sources. I see that the definition of egetenv in lisp.h is guarded 
with #ifdef USE_CRT_DLL. I try to run the command gcc, as I see it from make, 
but leave the -IUSE_CRT_DLL=1. It compiles OK and then make goes successfully 
forward until the end.

I run make install and everything seems OK.

I suggest you repair somehow the condition in #ifdef USE_CRT_DLL in lisp.h to 
not skip the definition when in Cygwin.

I also miss the information about newer versions of gmake etc. in INSTALL and 
README and I found the instructions about mounting text!=binary confusing. I 
had to try both ways and I still don't know if it's important at all.

Some (maybe) useful facts of my installation:
