I've long wanted the same thing.  I've written a patch to gdb which
lets you set the inferior's command-line arguments from the gdb
command line:

    gdb --args cc1 -ffoo -fbar ...

This patch is still in progress.  I need to rewrite it before the gdb
maintainers will accept it.

I also hacked gdb to let me do this.  One problem I ran into is that
gdb doesn't pass its std* file descriptors to the inferior.  Some work
there is required.

Anyway, we're closer to having this than you might think.  Even
without the I/O redirection stuff, the gdb patch is nice because it
makes cutting and pasting a simpler operation.
