    lib/libedit/makelist uses the filename given on the command line to
    generate an #ifdef statement in some of the header files it creates.
    Unfortuantely, if this filename includes characters that are not allowed
    in the #ifdef statement, cc complains.
      I discovered this in 1.0, but from my examination of the -current
    source code, it appears to be present there as well.
    Run the makefile with BSDSRCDIR and BSDOBJDIR in use, and have BSDSRCDIR
    have an illegal character, such as a -, in the path, so that make
    generates commands such as:
	sh /usr2/src-1.0/lib/libedit/makelist -h /usr2/src-1.0/lib/libedit/vi.c > vi.h
    I modified the line
	hdr="_h_`basename $1`"
    to send the output through sed to change the unwanted - to an _ in my case:
	hdr="_h_`basename $1 | sed -e 's/-/_/g'`"
    Perhaps a better solution would be to use tr to change or delete
    everything outside of a certain character range?
