;; The -std=c99 option is needed to avoid surprising FP behaviour in
;; bignum->flonum on x86, due to extended FP register usage.  Go
;; figure.  (GCC's -fexcess-precision=standard, which also works, is
;; not portable to other compilers, and older GCCs don't support it)
;; (compile -C -std=c99 -C -D_POSIX_SOURCE -s -O3 numbers.scm -j numbers)

;; Okay, that sounded better than it turned out to be in practice:
;; There seems to be no combination of feature test macros that
;; enable strlcat in the BSDs while enabling setjmp in Linux.
