[BUG] defining functions as macros when UCLIBC_SUSV3_LEGACY is off

[Amir Shalem]

Hey


UCLIBC_SUSV3_LEGACY patch causes breakage when compiling libstdc++-v3

because one of libstdc headers contains this code:

        size_t

        index() const ...


which causes gcc to barf since it tries to translate the macro index(), 
and fails.


I don't think we can replace the macros in <strings.h> and <string.h> 
with inlines,

because we can't assume C99 compiler in there.


Amir.
