Not available in the RTL POSIXIO layer, AFAIK. (Not much point, as the layer is
meant for device I/O, rather than file access...)

It's either a macro/inline in math.h, or a function in libm.

Just linking in the code *could* work, but it's rather likely that that would
result in various other things being pulled in, such as fprintf() and various
error handling code that can't be in a module. In that case, you have to rip
the code and remove or change the error handling code to suit your needs.
