Regex tests are ignored on windows

Updated description

They're broken on the bots: http://buildbot.rust-lang.org/builders/auto-win-32-opt/builds/5537/steps/test/logs/stdio

Needs investigation.

Original description

For example, the new regex tests just failed with this error

C:\bot\slave\auto-win-32-nopt-t\build\src\libregex\test\mod.rs:13:1: 13:27 error: Error code 127
C:\bot\slave\auto-win-32-nopt-t\build\src\libregex\test\mod.rs:13 extern crate regex_macros;
                                                                  ^~~~~~~~~~~~~~~~~~~~~~~~~~

I suspect that we're not marking the macro registrar with a dllexport linkage. Needs more investigation.

Additionally, that error is pretty bad.

I am less convinced that this is a syntax extension problem (small syntax extensions work for me), requires more investigation.

[alexcrichton]

Closing, the underlying cause is on osx as well, this will get fixed anyway when landing regexes.

Reopening and hijacking the description.

I just tried running make check-stage2-cfail-full TESTNAME=syntax-extension-regex-invalid after removing the ignore line and it seems to work fine:
