Right -- we have

billbug Solaris 11.4.81 CBE 04.2025 gcc 14.2.0
hake OpenIndiana / Illumos gcc 9.3.0
margay Solaris 11.4.42 CBE gcc 11.2.0
pollock OmniOS / illumos gcc 10.2.0

Hake actually says:
gcc (OpenIndiana 13.3.0-oi-2) 13.3.0

and pollock:
gcc (OmniOS 151054/14.2.0-il-1) 14.2.0

so it looks like the oldest is Margay's 11.2, which claims [1] to
support C11, though there are some bugs that were claimed fixed in later
releases of GCC 11.x related to alignment[2]. Perhaps relevant, but I
only searched the strings "align" and "c11" there, they may not apply to
our usage. At least the owner of margay and billbug is active, so we
can probably get the compiler in these machines updated if needed.

and further for 11.4, 11.5, 11.6.
