int main() and rule 6.3 - Lundin - 23-06-2008
I was wondering whether rule 6.3 applies to int main() or if this is should be a special exception? Ie should we write sint16_t main() or not?
Because if we state the width and signedness of main() we will suddenly make the app implementation-dependant and non-portable.
Also, ISO C strictly states that the return type shall be "int" on a hosted environment. One could interpret that as "it must be the primitive
data type int and no custom typedef".

In the definition of main, use the basic types int and char rather than fixed length typedefs.
This will be included in a future revision of MISRA C.
