Bugzilla Bug 20072

Every time I try to emerge tpctl, it fails.  Thinkpad-4.1 is installled and did
build correctly. And I was able to make and install tpctl-4.4 the old fashioned
way (make all, make install). 
BTW, thinkpad-4.3 and tpctl-4.4 have been released.

Reproducible: Always
Steps to Reproduce:
1.emerge tpctl
2.
3.

Actual Results:

This looks like one of those errno gcc-isms, see bug #16267. There's a good
chance that it's 
fixed in a later version, so I'll be updating the ebuilds shortly. 

This should be fixed now with the version bump. Please test, so I can close the
bug. 

Works for me now. Thanks for the help.

Cool, closing :)
