- Improved optimizations (~5% code-size reduction)

- Modified the provided GNU license to provide clarity that it applies solely to the cpp.exe pre-processor and to cygwin1.dll.

- Added -msgStyle=GNU option to the compiler. This causes warning & error messages to be output in GNU-style which is compatible with the default Eclipse CDT error parsers; this allows for click-on-problem-to-source-line capability.

- Added -msgLimit=NUM option to the compiler to allow the number of warning/error messages to be limited. The default is 50 before output is suspended.

- Added -ppOnly option to the compiler. Specifying this option forces the compiler to stop after only the pre-processing stage has been completed. If -out=<filename> has been specified the pre-processor output is directed there; otherwise it comes out on stdout.
