There are namespace constraints; and if you add a function to a header
and forget to properly bracket it, you get a nastygram from the standards
tests folks; for headers defined in the standard or indirectly included:
For UNIX03 mode:
When _XOPEN_SOURCE is defined with the value 600 and no other
feature test macros except _POSIX_C_SOURCE<=200112L are defined,
no other symbols than those defined or reserved by POSIX.1-
2001/XSH6 (including the XSI option) are made visible.
I got one for:
Illegal declared or 'typedef'ed symbol: mkstemps
(bug 6395215)
This helps people wanting to compile against strict POSIX and allows you
to use any symbol not declared by POSIX.

Since it does not give the proper declaration that is a bug.
