newlib and long-double question

[Necro Cow]

Hello.

I have recently discovered that the cygwin version I am using (1.7.7)
doesn't support many long-double function, like sqrtl, modfl, frexpl,
etc.

I have been reading on newlib's website, sourceware.org/newlib, that
as of version 1.18.0, such long-double functions are now supported.
(http://sourceware.org/ml/newlib/2009/msg01135.html)

What I can't seem to find out is, what version of newlib is in the
newest release of cygwin, and if it has this better support for
long-double functions.

One of the things I am trying to build with long-double support is
Perl-5-12.3, with use64bitint and uselongdouble options enabled (by
default they are not.) It requires functions such as sqrtl, modfl,
frexpl, which it seems are not available in the version of cygwin I am
using (1.7.7.)

Thanks for any help and insight.
