Our process for generating makefiles on Windows starts with the same Makefile.in and runs it through a C program that does no autoconf- style @FOO@ substitutions. However, if a line starts with @, it's replaced with a blank line. We don't actually use this fact at all currently, so far as I know, but it would let us make this change. (Or, if we switch from wconfig.c to wconfig.pl for generating the Windows makefiles, we could actually do real substitutions....) Ken
