[xemacs-hg @ 2001-09-18 05:04:26 by ben] fileio.c: Fix various C++ compile errors in Andy's recent code. callint.c, editfns.c, emacs.c, lread.c, redisplay-x.c: Fix sign-compare warnings. scrollbar-msw.c: Fix crash under MS Windows. See comment around line 223 for explanation. font-lock.el: fix problem when you insert a comment on the line before a line of code: if we use the following char, then when you hit backspace, the following line of code turns the comment color. configure.in: Don't use -Wshadow when compiling with g++ or you get buried in silly warnings. This patch was already applied but somehow got unapplied. Stephen?
