RegExp lib no longer compiles

[Dave Clarke]

The regular expresssion lib, located in modules/standard/Regex, no longer compiles.
This has slipped through testing because the test script was still located in the library directory, not in the test directory.

The error I get is:

RegexTest_src/Regex.encore.c:178:73: error: use of undeclared identifier
      'REG_EXTendED'
  ...result = regcomp(&((*_this)._enc__field_regex), _pattern_10, REG_EXTendE...

I suspect this is due to changes in the naming scheme for generated names.
