Last change on this file since 3359 was 3344, checked in by bird, 5 years ago
header.kmk,footer-pass2-compiling-targets.kmk: Introducing KMK_WITH_QUOTING as a simple 'quote' feature indicator. The SOURCES must be handled as a list of quoted files, or we cannot add chkstk.obj and such from an VC++ installation.
Property svn:eol-style set to `native` Property svn:keywords set to `Author Date Id Revision`
