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.
