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