Greetings,

I have an OpenGL/GLUT based program the compiles and runs just fine on
SGI Irix, Linux/Mesa, SunOS/Mesa, etc.  I am now trying to port it to
win32 using the Cygnus compiler (b18).  (BTW, I am running this on NT
3.51)

I fought my way through windows .dll hell, built my stub lib*.a's like
a good little borg and finally got an executable that links without
any complaints from the compiler about missing stuff.  But, my
assimilation was not quite complete.

When I tried to run the application on my NT 3.51 box, I received the
following message:

    The dynamic link library MSVCRT.dll could not be found in the
    specified path [long path deleted].

I went out searching the net and found a copy of this dll (my system
only had msvcrt20.dll and msvcrt40.dll ... again, windows dll hell.)

Anyways, now when I try to run my application, I get no complaints
about missing dlls, I get no printed output, I get no windows being
created---absolutly nothing, the application just ends.

I ran my program inside of gdb and it appears to be dying in
fhandler_console::is_console().  I have no clue what to do at this
point.  Any ideas?
