List of standard macros could/should depend on intended compiler/"dialect"

[rodinaarssen]

CDTParser.java contains a number of macros that are fed to CDT.

• Potentially, the whole parser may be parameterized with the intended compiler, fixing this list of macros along with the (standard) location of the standard library.

This list seems to now be moved to the AST.rsc file. However, it is still bias towards a Windows setup causing problems on other OS
