Title: Fixed gems 1’s compilation errors with newer cc

I fixed some compilation errors for gems 1, such that it can be compiled on Mac/Linux using:
* Apple LLVM version 5.0 (clang-500.2.79) (based on LLVM 3.3svn)
* cc (Ubuntu/Linaro 4.7.3-1ubuntu1) 4.7.3

My changes:
* Added function declarations.
* Added void return type.
* `#include ` => `#include `

PS.Since I don't know how to install the Utah Raster Toolkit on Mac/Linux, I haven't tested the AALines example.
