It's true that POSIX doesn't allow this, but actually it was legal in make for a long time. This suggestion is something I've thought of doing myself, and I've been working towards it for a while now, by first removing support for variable names containing spaces. Probably it's OK to finally implement this, at this point. _______________________________________________ Bug-make mailing list Bug-make@gnu.org https://lists.gnu.org/mailman/listinfo/bug-make
