Hi there, I decided that it would be good to make sure that I am up-to-date with Gambit 4.4 before I posted my web framework here for those who have expressed an interest and I am finding a destructive interaction when using the c-lambda form. With the code in the sequel and Gambit 4.4.0, if I compile thusly: $ gsc -:s -link bug.gambit *** ERROR IN MAP -- invalid syntax () but it compiles fine if I omit the -:s option. Now obviously, the example does not require syntax-rules macros, but the full framework certainly does. Is there a known incompatibility here? The text concerning define-syntax hints at such a possibility, but the actual interaction is unclear. david -- GPG Public key at http://cyber-rush.org/drr/gpg-public-key.txt ; Null module for: Prelude (c-declare " #include <sys/time.h> #include <time.h> ") (c-define-type timeval (struct "timeval")) (c-define-type timeval* (pointer timeval)) (define make-timeval (c-lambda () timeval* "___result_voidstar = ___EXT(___alloc_mem)(sizeof(struct timeval));")) (define timeval.tv_sec (c-lambda (timeval*) int32 " ___result = ___arg1->tv_sec;")) (define timeval.tv_usec (c-lambda (timeval*) int32 "___result = ___arg1->tv_usec;"))
