Hmm, OK, so there's two issues here, which is why some of my previous
instructions might not have worked:

1) I originally developed this with the 2.4.0 wxwindows stuff, and some
things might have changed in 2.4.1.  (like the "windows.h" thing).

2) I didn't use ./configure for wxwindows build, I used makefile.g95.

Anyway, before the whole baby thing, I got 2.4.1, and tried to do the
"makefile.g95" build, which didn't work.  I looked into it a bit, and
apparently that's not the "preferred" way to do the wxwindows build (I
guess they're not maintaining those makefiles anymore), so I build with
./configure, and then ran into some of the same problems that y'all
did.  So, I have steps 1 - 4 of the README directions for this already
written, but didn't get to finish them, because I realized that I ought
to make the Makefiles smarter, so some of the steps wouldn't be
necessary.

I.e. ./configure installs the library as libwxmswd241.a, while the
makefile.g95 build make libwxmswd.a, which seems like it should be a
symlink or something to the versioned library.  The MSWin wx stuff
doesn't have "wx-config" as far as I can see, so it's harder to make the
link command find the library, etc.

Okay, all that's definately not helping anyone :)

For your question, the link line is looking for -lwxmswd and it's
looking for it in $WXWIN/lib as libwxmswd.a  .  The versioned file you
have (libwxmswd241.a) should work fine if you rename it, and put it in
$WXWIN/lib.

On the other hand, I won't be in the office tomorrow (and don't have
Win32 boxes at home), so if people want to figure out what code changes
are needed to make the build more "version independent", and better
instructions, here's what I wrote so far:

=======================
Building WXWindows on Win32, with MinGW/Cygwin:

Here's what I did to buld wxWindows 2.4.1, on Win2K, using MinGW and
cygwin.
This may not be the best way to do this, but it worked for me.

1) First, I have both cygwin and MinGW installed (including cygwin's
"make"), and MinGW
ahead of cygwin in the PATH.

2) I got the wxWindows 2.4.1 ZIP archive (not the -setup version), and
unzipped
it into the
root of my "c" drive.  The path to this is (from cygwin or MinGW)
c:/wxWindows-2.4.1

3) set WXWIN environment variable to point to this location, by editing
my .bashrc, and then
        reloading my bashrc.  here's the line:

        export WXWIN="c:/wxWindows-2.4.1"

4) as in the directions, just did this:
        cd $WXWIN
        ./configure --disable-shared
        make

5)
