Re: [Ada] multilib patch take two => multilib build working


This will need some additionals tests on MULTILIB in the LIBGNAT_TARGET_PAIRS
machinery (3 files for x86 vs x86_64, solaris looks like already done, powerpc
seem 32 bits only right now, s390/s390x, others?) but it doesn't seem like a
blocking issue with the proposed design since each MULTILIB rts build has
completely separate directory and stamp (through RTSDIR) so there is no
possibility of conflict through sharing.

Do you agree with this assessment?

Unfortunately not. The solaris bits are just "factoring" a bit the definition of LIBGNAT_TARGET_PAIRS. The actual multilib definition can be arbitrary, for example you can have big-endian/little-endian multilibs. If the design is explicitly to have constants spelled out in system-* files (instead of having them, for example, in Autoconf macros), there is not much that you can do.
