Help compiling TCL 8.0.3 with GCC-2.95.2 Upgrade


I am trying to compile TCL 8.0.4 using Cygwin b20 with GCC-2.95.2 downloaded from
www.xraylith.wisc.edu/~khan/software/gnu-win32/.
 
I also downloaded a patch Tcl 8.0.4 diffs from Mumit Khan at the same site and
applied it. 
I also had earlier downloaded and installed Munit's binary build for
Tcl/Tk 8.0.4, Tix, and BLT 2.4g for Cygwin b20 from the same web page.
However I now need a complete source tree for another project that depends
on being able to access the tclusing more then just tclConfig.sh.
 
I then attempted to build tcl8.0.4 from the patched sources.
Note: Complied with -U_WIN32 added to Makefile after running configure
I think this is necessary otherwise generic/tclPort.h includes 
"../win/tclWinPort.h" instead of "../unix/tclUnixPort.h"
 
I received the following warnings and errors.
The library appeared to build but is unusable because of the many undefined
references.
 
Been working on this with only a couple hours sleep in the last
two days and could use some suggestions.
 
Hope somebody can help.  TIA Allan Iverson
