FYI, the claim "Sun C 5.8, a C99 compiler that does presently produce 
working Emacs builds" is pure fantasy, aka fabricated evidence.  I had 
some free time today, I digged in my archives, and found a copy of Solaris 
10 and Sun Studio 11, which I installed in a VM.  The last Emacs version 
for which Sun C 5.8 produces a working Emacs build is... Emacs 24.

Much ado about nothing.  Somehow, I'm not surprised.
