Conflicting declaration of C function 'void sleep()'

Quite similar to existing topic https://developer.mbed.org/forum/bugs-suggestions/topic/17173/ but different in that the source of the error strangely seems to be coming from the mbed lib itself:

[Error] sleep_api.h@44,6: conflicting declaration of C function 'void sleep()'

Some info about my environment: I'm experimenting with some libs which *might* yank in unistd , but should be #ifdef'd out... hopefully

Even if that's an issue, would the error look like what we're seeing here?
