[cfe-dev] Integer and Float type definitions with respect to bits number

[Halfdan Ingvarsson]

Have a look at <stdint.h> for integer types. This should be a part of 
your standard library for any C99-compliant compilers. For Windows, 
they're included in MSVC2012 onwards.

float and double are always defined to be 32- and 64-bit, respectively. 
Beyond that you're in a platform-specific extension area. See, for 
example: http://gcc.gnu.org/onlinedocs/gcc/Floating-Types.html
