/*
* Calling convention extended explanation
* GCC triggers a warning on arm processors "warning: 'cdecl' attribute directive ignored"
* From the documentation they state it is only applicable for Intel 386
* https://gcc.gnu.org/onlinedocs/gcc-4.7.2/gcc/Function-Attributes.html
* On the Intel 386, the cdecl attribute causes the compiler to assume that the calling function
* will pop off the stack space used to pass arguments.This is useful to override the effects of the - mrtd switch.
