ok, that should work. We're going to at least try to get a more recent gcc on 111, will be in /opt/cfarm/lhvn/packages/LHVNgnuCC1030 if we can get that version to build

However, my old notes mention OBJECT_MODE and COMPILE_BITS as environment
variables which influence the IBM toolchain.
IIRC, their use could/should eliminate the need for `-q64` and `-X 64`
arguments in the 64-bit cases listed by Bruno.

See, for instance,
https://www.ibm.com/docs/en/xl-fortran-aix/16.1.0?topic=environment-default-bit-mode
OBJECT_MODE works fine for xlc.

But it does not work with gcc:

   $ OBJECT_MODE=64 gcc hello.c
   Assembler:
   /tmp//ccK4WLFO.s: line 8: 1252-191 Only .llong should be used for 
relocatable expressions.
   /tmp//ccK4WLFO.s: line 56: 1252-191 Only .llong should be used for 
relocatable expressions.
   $ echo $?
   1
