Let's all sing along:  o/ Read the ****ing manual / Read the ****ing

The DJGPP distribution comes with a program called 'redir' that does
exactly what you describe.  Type 'redir' without arguments for the full
syntax to use.  The FAQ also describes 'redir' in chapter 6.10:  "How to
redirect GCC messages to a file."  Basically, here's what to do:

  redir -o err.log -eo gcc ...

The above redirects both stdout and stderr to the file 'err.log'.
