I think this is because bash runs in `non-interactive' mode when Emacs
spawns a compile process.  You can try defining BASH_ENV in the runtime
environment of Emacs.  The `BASH_ENV' variable is expanded by bash, then
it tries to read commands from this file.  So you can set its value to
something like:

    BASH_ENV='~/.bashenv'

Then add the aliases of your non-interactive bash sessions to that file.
