Created attachment 267227 [details, diff]
Fix compilation.

libgcrypt ebuild shouldnt be allowing flag munging in the first place

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.
