C99 did introduce one thing I use: <stdint.h>

Beyond that, I still code strict C89.  I simply treat the language itself 
as ossified.  I also still make assumptions about the compiler that might 
not still be true, so for example

  unsigned short a;
  unsigned char b;

  b=0xFF;
  a=b<<8;

I expect to return 0 even though the logical answer is 0xFF00, and I 
_always_ code it like this:

  b=0xFF;
  a=b;
  a<<=8;

or alternatively

  b=0xFF;
  a=((unsigned short) b)<<8;

and there's other defensive stuff I do.  I honestly don't see the point in 
the other changes to the language and feel they take C away from what it 
has always been.
