header.kmk@ 3424

Last change on this file since 3424 was 3424, checked in by bird, 5 years ago
header.kmk: Must unexport PATH_DEVTOOLS or the warning will trigger for every command when it's already in the enviornment when kmk is started. Instead export KBUILD_DEVTOOLS if we're using PATH_DEVTOOLS to figure out its value.
Property svn:eol-style set to `native` Property svn:keywords set to `Author Date Id Revision`
