Indeed it's for an old Solaris version. I'm ok if you don't want to
include patches for old platforms. Anyway, a correct build for Solaris
9 is only a couple of math functions away, so I think it is still
reasonable. Up to you. I've pasted the patch at

http://paste.call-cc.org/paste?id=1d9a79658c2bb91f99d7154395ee37d2cdb10bf7

for users which might need it (very few I guess). It would need some
tweaking as Florian pointed out but if it's not going to be included I
don't care about floating numbers.

Gcc has the same issue on Solaris 9 since the functions are missing in
libm. On newer versions (Solaris 10, 11) they are correctly
implemented.

As regarding the proposal to drop suncc on modern Solaris versions (if
I understand it correctly), I disagree. Much like I would disagree if
you were considering dropping MSVC on Windows (if such thing existed).
