<stack trace>

Poking around in Linker.java, line 517 I observed the regular expression to find a version number appears different and possibly broken compared to the regex's used in other cases.

Specifically, it appears to be missing a quoted backslash in the last number matching term:

final Pattern p = Pattern.compile( "\\d+\\.d+" );

I suspect that it should be:

final Pattern p = Pattern.compile( "\\d+\\.\\d+" );

I suppose g++ is the overwhelming use case and CC is abandoned for g++ when it fails like above.

Thanks for the heads up!
