NetBSD thor 1.5.3 NetBSD 1.5.3 (GENERIC) #0: Tue Aug 27 17:42:36 EST 2002     awhite@thor:/usr/src/sys/usr/src/sys/arch/i386/compile/GENERIC i386
>Description:
In bsd.sys.mk, the dependency code uses the pattern ${CXXFLAGS:M-[ID]*} to match and extract include paths.  Unfortunately, this works fine for -I/this/path, but breaks when the equally legal (to the compiler) -I /this/path is used.  Instead, you get mkdep -a -I -I -I ...
>How-To-Repeat:
Add include paths to COPTS using -I /this/path syntax, and make depend.
>Fix:
Pattern is obviously too restrictive, but fix is not obvious.  Other alternatives may be available, including a mechanism to abort with a useful error message when a -I /this/path is used, allowing the user to edit makefiles.  Of course, this negatively impacts portability.
