This function is not visible if some other symbol is defined like
_POSIX_C_SOURCE, or _ANSI_SOURCE, or _XOPEN_SOURCE etc, since only
symbols that are defined by the respective standards are supposed
to be visible.

The netsurf developer should not be defining _FOO_SOURCE if he intends
to use symbols outside the scope of _FOO_SOURCE. He should also be compiling
with warnings on so that problems like this become apparent :-)
Look in <sys/featuretest.h>
