Yes. We still support back to GCC 3 and friends. The easiest way to
test the old compilers is to stand up a VM with the old OS.

It's fairly easy to do. Download Ubuntu 4 from
https://old-releases.ubuntu.com/releases/. Install Ubuntu 4 into a VM.
Once you log in, run the following command to fix Apt:

    sed -i 's/archive.ubuntu.com/old-releases/ubuntu.com/g'
/etc/apt/sources.list

Now Apt works and you can install packages.

Git is missing, and SSH is antique. So they are the programs I install
and update through my build scripts.

Yeah, it's that __THROW thing again. I added the following to each
system header file that produced an error:

#ifndef __cplusplus
# undef __THROW
# define __THROW
#endif

I also caught an error about _IO_FILE like at
https://www.mail-archive.com/bug-gnulib@gnu.org/msg39100.html. Gettext
needed 
https://git.savannah.gnu.org/gitweb/?p=gnulib.git;a=commitdiff;h=b2d4b6c87827e34a694278d085a31508af052a37.

Maybe it's time to release a new Gettext?
