Re: Vim using wrong $PATH to find gcc?

Yes, :set shell? prints the path to tcsh.

Yes, this was the problem.

The shell Vim invokes again sources my .cshrc file, where I had:

# $PATH ^= /opt/sfw/bin (more recent Vim versions)
# $PATH += /usr/atria/bin (clearcase paths)
setenv PATH '/opt/sfw/bin:'$PATH':/usr/atria/bin'

I've changed this to:

# $PATH ^= /opt/sfw/bin (more recent Vim versions)
if ( $PATH !~ */opt/sfw/bin* ) then
setenv PATH '/opt/sfw/bin:'$PATH
endif

# $PATH += /usr/atria/bin (clearcase paths)
if ( $PATH !~ */usr/atria/bin* ) then
setenv PATH $PATH':/usr/atria/bin'
endif

And now it works! Or at least,

:echo system('which gcc')

gives the expected result.

Thanks for the hint!
