Fix compilation.
Comment 2 SpanKY gentoo-dev 2011-03-27 14:29:50 UTC 
libgcrypt ebuild shouldnt be allowing flag munging in the first place
Comment 3 Dane Smith (RETIRED) gentoo-dev 2011-04-06 18:39:42 UTC 
The problem isn't necessarily Ofast, it's the fact that flag munging is making it into -O1fast.

That is not a valid identifier.

I've revbumped this to 1.4.6-r1 in CVS and removed the stupid flag munging. Please try that and confirm / reject -Ofast before I go and filter that as well.

Closing as test requested. Please append whether or not this fixes the issue.
Comment 4 Xiangyan Sun 2011-04-07 06:47:20 UTC 
The compilation problem resolved with dev-libs/libgcrypt-1.4.6-r1 and dev-libs/libgcrypt-1.5.0_beta1-r1.
