How long is your Path? On a typical Windows machine, it tends to be quite long, what with all kinds of packages that add to it at will. It's nothing as short as "/usr/bin:/usr/local/bin" on Unix. No, sorry, I cannot accept a solution that searches PATH before each command. Perhaps we should introduce a new interface to the stored variables, which would store a canonicalized (a.k.a. absolute) file name (computed only once) for variables, like SHELL, that point to file names. Then those parts of the code that need SHELL for running programs could access that canonicalized file name instead of the value of SHELL instead. _______________________________________________ Make-w32 mailing list Make-w32@gnu.org http://lists.gnu.org/mailman/listinfo/make-w32
