[xemacs-hg @ 2001-05-12 11:16:12 by ben] event-msw.c: eliminate cygwin warnings. dired.c, syswindows.h, win32.c: find the Net* functions the hard way to avoid errors on win 9x. find-paths.el: fix error with null EXCLUDE-REGEXP. font-lock.el: fix problem reported by hrvoje with buffers starting with a space. lib-complete.el: add a variable to control where `find-library' looks, analogous to `find-function-source-path'. etags.c: new version from Francesco. Makefile.in.in: i'm getting real tired of incomplete commits. is this getting worse or something?
