Hi all,

I have been testing what I think is the latest version of Mingw32.  It 
installs under a directory called GCC-2.95 and the date on many of the 
files is July 31, 1999.  I have a Intel 200 Mhz computer, with Win95 (last 
version with USB support).

I finally compiled a very large program that normally had a file size of 
6-7 Mb (under the Absoft F77 compiler).  When I compiled under g77, the 
size was less than 1 Mb...that suprised me. Next, I compared run times 
inside of a DOS window that was created from within Windows, and noted that 
they were about the same.  The final test was where I got a bit 
confused.  I have a Tcl/Tk GUI for running this program.  Output that would 
normally appear on a DOS command line is piped to a console program (got it 
straight out of Brent Welch's book "Practical Programming in Tcl and TK", 
page 234) that allows the run to be observed.  At this point the 
performance diverged.  The g77 compiled program appeared to interact poorly 
with the console.  It would eventually complete, but it really looked like 
it was not supposed to be run from there.

I thought this g77 was meant for compiling programs for Windows 
applications.  Did I miss something?  Was I suppose to link with some 
special library?  Or am I just plain using this incorrectly?

Thanks in advance,

Mike O'Melia
