qemu-0.7.0.ebuild has a typo on line 121 -- it should be "if use !softmmu" instead of "if use ! softmmu". Reproducible: Always Steps to Reproduce:
That is a valid usage, I'll change them to "! use useflag" since is nicer for style. Thanks anyway for pointing out.
Thanks for the quick response, but are you sure that it is a valid usage? On my machine, it results in "QA Notice: USE Flag '' not in IUSE" and the warning message is still printed even though I have softmmu in my USE flags.
I'll double check why that message appear in the mean time I'll move to the style "! use foo"
