UPDATE: This just in...

http://gcc.gnu.org/onlinedocs/gcc-3.4.1/gcc/Other-Builtins.html#Other%20Builtins

"The ISO C99 functions ... cabsf, cabsl, cabs, cacosf, cacoshf, cacoshl,
cacosh, cacosl, cacos, cargf, cargl, carg, casinf, casinhf, casinhl,
casinh, casinl, casin, catanf, catanhf, catanhl, catanh, catanl, catan,
cbrtf, cbrtl, cbrt, ccosf, ccoshf, ccoshl, ccosh, ccosl, ccos, cexpf,
cexpl, cexp, cimagf, cimagl, cimag, conjf, conjl, conj,..., cpowf,
cpowl, cpow, cprojf, cprojl, cproj, crealf, creall, creal, csinf, csinhf,
csinhl, csinh, csinl, csin, csqrtf, csqrtl, csqrt, ctanf, ctanhf, ctanhl,
ctanh, ctanl, ctan ... are handled as built-in functions except in strict
ISO C90 mode (-ansi or -std=c89)."

Sounds like I just need to wait for gcc 3.4.  Is there a build of it
available for cygwin yet?
