//! 
//! For some reason QNX gcc 4.8.3 is missing some C++ standard string fonctions.
//! Well they are there but are between ifdef that takes them out.
//! Has to do with C99 compatibility but it looks more like an oversight.
//! This header contains some of those fonctions which have been copied
//! from the system header files.
//! This might cause compatibility issue in the futur  when these fonctions becomes
//! present, just have to add some smart #ifdef to makes it compatible.
//! That's is why these won't go in std_c as they are "temporary"
