Sorry, I am a complete noob to all this make/install/gcc stuff, I am just trying 
to make a fresh build of a DLL I have used for years to see if it resolves a 
problem.

I installed cygwin 1.7.1 today on a windows 7 laptop.

The directions for my library are great:

"VER=8.4.12
SRCDIR=`pwd`

cd $SRCDIR/tcl$VER/win
env 'CC=gcc -mno-cygwin' ./configure --enable-threads
make libtclstub84.a

cd $SRCDIR/tk$VER/win
env 'CC=gcc -mno-cygwin' ./configure --enable-threads
make libtkstub84.a

cd $SRCDIR/Togl
env 'CC=gcc -mno-cygwin' ./configure --with-tcl=../tcl$VER/win --with-
tk=../tk$VER/win

make"

That's from doc for the lib which is Togl, an OpenGL add-on widget to Tcl/Tk. 
Unfortunately the mailing list does not seem active, because:

The first env command responds "C compiler cannot create executables" and refers 
me to the config.log. That has a few lines showing the -mno-cygwin flag has been 
removed and telling me to use a mingw-targeted cross-compiler.

Not sure if those are warnings or that is why later what looks to be a hello-
world-like little C compile reports failure leading next to the "cannot create 
exes" message.

Googling did turn up a long-ago discussion mentioning deprecating no-mingw (and 
to my relief that this is not something poor know-nothings like me should 
encounter) but the obvious solution ("a mingw-targeted cross-compiler") did not 
work out two ways:

1. Just googling that did not cause anything to jump out at me.
2. I am wondering if this is a cross-compiler situaton, since I am on Windows 
trying to build a windows DLL.

Any clues greatly appreciated!
