Writing portable code in C pretty much requires you to do hefty 
compatibility layers. Many projects use typedefs to get proper-sized int 
variables (you can't use stdint.h, as MSVC doesn't implement it, as of 
MSVC 9.0). Anything more complex than basic I/O requires the use of 
other, largely incompatible layers, for common things like 
multithreading, asynchronous I/O, network I/O, etc. Let's not even get 
into basic GUIs.

And even then, a careful reading of the C standard would reveal that it 
gives very few absolute requirements of stuff, so that I could make 
size_t be an 800-bit integer and still follow the standard, as well as 
probably breaking everyone's so-called "portable C" code.
