no, Solaris 9 support was removed in GCC 5 already. The only version
supported by trunk is 11.4; 11.3 isn't but I won't actually remove
support until Solaris 11.4 systems have been added to the cfarm (which
should be soon).

Thanks.

True. However, it can be difficult to get patches upstream for OS
versions not remotely supported in LLVM (which has been 11.4-only for
years).
