-Contains the UnixCCompiler class, a subclass of CCompiler that handles
-the "typical" Unix-style command-line C compiler:
- * macros defined with -Dname[=value]
- * macros undefined with -Uname
- * include search directories specified with -Idir
- * libraries specified with -lllib
- * library search directories specified with -Ldir
- * compile handled by 'cc' (or similar) executable with -c option:
- compiles .c to .o
- * link static library handled by 'ar' command (possibly with 'ranlib')
- * link shared library handled by 'cc -shared'
