This issue came up on the dfly-user lists a month or so back,
looks like the GNU C library is more C99 compliant w/r/t floating point
functions than any of the BSDs, so linux / c99 centric applications are
hitting portability snags when someone tries to build on a bsd

At the time, it seemed that NetBSD had the most C99 compliant set of
functions compared to Free/Open/DF, but still not all of them were
implemented. Not sure of the state / licencing / availability of
Apple's C library, might be worth investigating..

DF has since synced with NetBSD 4,
I'm unsure of the progress in any of the BSD's since then..
