The following syntax interpretes the source as a C file.

	gcc src.c    (c extention)

The following syntax interpretes the source as a C++ file.

	gcc src.C    (capital C)
	gcc src.cpp  (cpp extention)
	g++ src.cpp  (g++ program called)

The default output of gcc is a dynamically linked program. This means that
it will have dependencies on certain libraries from the system.

The alternative is a statically linked program which compiles all the code
needed into the program. This option flag is (-static) and makes programs
larger than a dynamically linked program. This would be a good option for
boot floppys or programs where libraries may not be present on a system.


To define somthing when compiling which will change the code of the program,
use the -D option followed by the define (no spaces b/w -D and the define).

/* file.c */
#ifdef SOMETHING
	code...
#endif

$ gcc file.c -DSOMETHING
