Replace filename from compilation buffer errors

[Filippo Argiolas <filippo.argiolas@gmail.com>]

Hi I am working on a project that builds in a temporary workspace.
I'd like to take advantage of Emacs compilation mode, especially jumping
from an error to the locus inside the file.

Problem is it jumps in the file inside the temp workspace instead of the
one in the source tree.

Is there a way to achieve a simple string substitution in the file name
before jumping while keeping existing compilation regexps?

Thanks,
Filippo
