So what? :-) My understanding of Han-Wen's report is that FreeBSD has `complex double' but does not provide `clog ()' et al. as part of its libc. Thus, checking for the presence of those functions may be necessary _even if_ complex doubles are available. C99 (Section 7) does not seem to say whether these functions have to be in libc. Thanks, Ludovic. _______________________________________________ Bug-guile mailing list Bug-guile@gnu.org http://lists.gnu.org/mailman/listinfo/bug-guile
