I'd like to do LTO, I think it's a good idea, except that it seems
this feature is not quite ready for prime time in MinGW. Maybe later
(with later zlib versions).

OTOH I'm not so fond of -fprofile-generate. There's nothing wrong with
it for a domain-specific application with restricted kinds of input,
but here zlib is supposed to handle every conceivable kind of input
and compression parameters in a well-balanced manner. Tailoring the
executable for source code (such as the Linux kernel), or for any
other kind of specific inputs, will put everything else at a
disadvantage.

So, is the DLL archive that I prepared, good to go?
http://cosmin.users.sourceforge.net/testing/zlib125-dll_ASM.zip
(to be renamed as zlib125-dll.zip)

Best regards,
