My point wasn't about the future - *today* a compile with normal settings
doesn't work, on a machine with a reasonable amount of ram. Who does it help
if one person can get postgres to compile with some applied magic - normal
users won't.

And it's not a cost free thing to support, e.g. I tried to build because
solaris with suncc forces me to generate with_gnu_ld when generating a
compatible Makefile.global for pgxs with meson.
