Yes, that's what I mean.

Yes, it does that, but takes 400 lines of shell script to do so.

If you want "relatively easy ways to build GCC painlessly" then you
can do it with nine lines of shell commands.

Or in about 80, for any non-prehistoric version, with no config file
needed (just a single option to the script, the release number or
snapshot name to build):

My point is just that there are already easier ways to do it, not only
by using spack or the OpenCoarrays build script.

N.B. your https://github.com/wyphan/gccprefab/blob/main/gcc12.cfg
config file says "Latest GCC 12 Release" but actually builds from the
tip of the branch, not a release.
