Packaging gcc for Windows is more difficult than packaging gcc
for Unix-like systems.
It's not hard; it should really have used a path relative to B's gcc.exe.

It would still pick A's gcc.exe if typing an unqualified 'gcc' by
itself, but how does Linux solve this problem when you have two gcc's to
choose from?
One can use modules:
$ module use --append /nfs/Software/module/my-common/modulefiles[...]
$ module load gcc/11.3
On Ubuntu, the "module" command isn't installed by default. You can
install it via the "environment-modules" package. (I've used it
on SGI and Cray systems, where it originated, but not on Ubuntu,
and not in the last couple of decades or so.)
