Mr. Paul,

[ This is entirely non-Cygwin-specific. ]

Apart from the FORTRAN business, about which I know nothing...

If you're running the ordinary BASH-in-a-console-window Cygwin, which is 
the default for a Cygwin installation when you launch using the "Cygwin 
Icon" on the desktop or in the Start menu, then you can set the amount of 
scroll-back in the window's Properties dialog.

The window configuration (font, colors, screen size, scroll-back buffer 
size, etc.) can all be preset permanently via the Properties dialog for the 
shortcut that launches Cygwin. If you use RXVT, then the control of these 
parameters is via invocation options to "rxvt.exe," whose documentation you 
should read to learn how to control these attributes.


Secondly, the reason I/O redirection didn't capture the compiler's error 
messages is that errors are sent to the "standard error" output, which 
requires a variant redirection syntax:

BASH & ash:

         command >normalOutput
         commandThatProducesErrorMessages >normalOutput 2>errorOutput
         commandThatProducesErrorMessages 2>errorOutput
         commandThatProducesErrorMessages >allOutput 2>&1

Note: The "2>&1" must come after the ">allOutput".

CSH / TCSH:
         command >normalOutput
         commandThatProducesErrorMessages >& allOutput
