Certainly it looks the case. It might also be worth actually looking at
the two flighting system header files - occasionally sections are
controlled by macros like this:

extern void foo(int bar)
static void foo(char bar)

where alternative function prototype definitions are chosen based
on macros. It might be possible to resolve the conflict by defining
a suitable macro during ./confgure. with something like this:
    CFLAGS="-D_XOPEN_SOURCE" ./configure

(in fact posting the two files somewhere or even e-mailing in
might be a good idea - I am not promising I'll look at them
in time though, but somebody else might have the time to do
it, so it might be a good idea to put it up on a URL and wait...).
