First off, there was a typo in my previous response:
ISC_SOCKET_MAXSOCKETS should have been ISC_SOCKET_FDSETSIZE.

Replacing the macro name with the correct one, and assuming you're
using a bsh variant such as zsh and bash:

% STD_CDEFINES='-DISC_SOCKET_FDSETSIZE=4096' ./configure

But again, I'd rather strongly recommend 9.3.6.  Then you won't have
to care about ISC_SOCKET_MAXSOCKETS or any other annoying details
about FD consumption in the first place.  There should be no reason
for someone considering an upgrade to 9.3.5-P2 not to rather use
9.3.6.
