   I'm sure this is a very simple thing, but I'm having trouble finding
   the answer.

   I generally like to redirect output to a text file when I compile.
   The standard '>' redirect doesn't seem to work when I use gcc.  How
   can I redirect the list of warnings/errors produced by gcc to a text
   file?

From the FAQ:


**Q*: I want to read all the error messages that GCC throws on me, but they
are so many that I can't keep up.  How can I redirect them to a file?*

**Q*: When I add `-v' to the GCC command line, how can I put all the
voluminous output into a file, so I don't miss anything when reporting a
problem?*

**Q*: I have this nifty graphics program which bombs from time to time, but
the registers and traceback info is hidden by the graphics display.  How can
I see it?*

*A* :  There are several alternatives:

  a. You can use a shell smarter then `COMMAND.COM', such as `4DOS', which
     knows how to redirect standard error stream to a file.  4DOS is
     shareware and can be found on SimTel, e.g.
     ftp://ftp.coast.net/SimTel/msdos/4dos/.

  b. You can also run your program under any one of the programs which save
     the output of programs they spawn in a file.  I suggest using a program
     called `SCRIPT', which is similar to its Unix namesake.  It has an
     advantage of saving everything which goes to screen *and* showing it on
     the screen at the same time.  You can find SCRIPT on SimTel, e.g.
     ftp://ftp.coast.net/SimTel/msdos/screen/script11.zip.

NOTE THIS ONE:

  c. Or you can use the `REDIR' program which comes with DJGPP.  It also
     redirects standard output and/or standard error to a file, but you don't
     get a chance to look at the output while the program runs.

Check the Info docs for options.  Gcc writes to stderr which DOS cannot 
redirect, but REDIR can.
