Had error compiling mysql versions and needed tcp-wrappers r4 wich has the stdc patch but couldn't get emerge to see it. r5 is masked but r4 wasn't. found in default-1.0/packages a line "<=sys-apps/tcp=wrappers-7.6-r3 which wouldn't let r4 emerge. Changed to r4 and can emerge and mysql compiles correctly now. System: Gentoo 1.2 w/ gcc-3.2.1 as default compiler.
Update?
annoying bug.
