GCC is very good (generates magnificent code and is very useful to port
Unix programs) but you need a lot of memory and harddisk space (4 megabyte
memory is about the minimum I think). GCC is actually three compilers in
one: normal Ansi C with many many GNU extensions, a extensive C++ compiler
and an Objective C compiler.

If you're only concerned about portability to other GCC compilers on other
platforms you can use some of the nice extra C features. Here are some
examples:

- A 'long long' type for 64 bit integers.
- You can use constructions like (a > b ? c : d) = 3; which assigns 3 to
  'c' if a > b or 3 to 'd' otherwise.
- A new 'typeof' command to get the type of an identifier. For example:
    int a;
    typeof (a) b;
  This can be very useful in macros (if you want to write a general and safe MAX
  macro for example)
- You can also use {} in expressions, allowing things like:
     a={int b,i; for (b=i=0;i<4;i++) b += i; b}+4;
- And a lot more I don't remember
