Marc:
I have the following definitions in a file I'm using when updating Gambit's trigonometric (and adding hyperbolic) functions:
;;; #include <math.h> is in gambit.h
(define ##scalbn (c-lambda (double int) double "scalbn")) (define ##ilogb (c-lambda (double) int "ilogb"))
(define ##flsinh (c-lambda (double) double "sinh")) (define ##flcosh (c-lambda (double) double "cosh")) (define ##fltanh (c-lambda (double) double "tanh"))
(define ##flasinh (c-lambda (double) double "asinh")) (define ##flacosh (c-lambda (double) double "acosh")) (define ##flatanh (c-lambda (double) double "atanh"))
(define ##fllog1p (c-lambda (double) double "log1p")) (define ##flexpm1 (c-lambda (double) double "expm1"))
It would be really helpful for me if these could be added to gambit.h, the compiler, and _num.scm; then I could just propose patches to _num.scm for my changes, which will come in stages.
Also, it would be good to know whether these are available on all systems that Gambit runs on.
