Not sure I fully understand your statement here. Currently there are
two types of headers - A) provide official (like) implementation, and
B) that wrap around existing ones.
Example:
 A) include/c99/* provides stdint.h & co for MSVC 2012 and older as
they lack the headers.
 B) include/c99_math.h provides compat wrapper, as MSVC 2013's math.h
is not in C99 land yet.

About using those - everything is handled already. Where needed the
extra include is added by the build (for A) and where the code is
known to be build with MSVC a header from B is used rather than the
system one.

Hope that clears things up.
