2.1. Important gcc Flags

`-ansi`	This flag tells the compiler to enforce ANSI C standards
`-pedantic`	More pedantic ansi, warnings for stuff you probably didn't mean.
`-Wall`	Show all reasonable warnings (there are more).
`-g`	Produce debug information, necessary for debugging.
`-llibrary`	Links to a standard library. Use `-lm` to load the standard maths library.
`-c`	Compile or assemble the source files, but do not link. The compiler output is object files corresponding to each source file.
`-S`	Compile only; output assembly code.
`-E`	Pre-process only. Output pre-processed code.
`-Dmacro`	Define a macro, one can also use `-Dmacro=val` in order to assign a value for the macro. This will be used for preprocessing all files.

When compiling, I recommend (and Kimchi demands) compiling with:
gcc -ansi -pedantic -Wall file1 [file2 [file3...]] -o output
