A follow-up on this.
Cygwin has recently[*] added support for C99 complex math, taken from
NetBSD with code that is very similar to that from Steven Moshier
available via http://www.moshier.net/c9x_readme.html.
That code isn't entirely right, especially not at the cuts on the
inverse functions where C99 mandates what cut is used (and neither
glibc nor Mac OS X have it correct).
I would expect that the current R-devel (I mean an SVN checkout now)
should build on your platform, substituting the missing functions by
ones based on earlier code. There may be a few more tweaks required,
but I have corrected several errors in the versions FreeBSD would have
used in R 2.12.1.
[*] AFAICS not yet released in Cygwin, but in newlib 1.19.0.
