This brings to mind something that I have wondered about.

I often see advice elsewhere, and in other peoples programs,
suggesting hiding all C "fundamental" types behind typedefs such as

typedef char CHAR;
typedef int INT32;
typedef unsigned int UINT32;
typedef char* PCHAR;

The theory is that application code which always uses these typedefs
will be more likely to run on multiple systems (provided the typedefs
are changed of course).

I used to do this. Then I found out that C99 defined things like
"uint32_t", so I started using these versions instead. But after
following this group for a while I now find even these ugly and don't
use them unless unavoidable.

What do people here think is best?
