Subject: long file name bug in 'make'
Reply-to: drg AT uiuc DOT edu


Here is a bug in make connected with long file names.  It only makes one of
the two files required.

    >> set lfn=y

    >> cat makefile
    all: asdfasdfasdf.oo asdf.oo
    %.oo : %.d
	    @echo making $@
    asdf.oo : asdf.sig
    asdfasdfasdf.oo : asdfasdfasdf.sig

    >> ls -l
    total 2
    -rw-r--r--   1 dan      users           0 May 29 12:07 asdf.d
    -rw-r--r--   1 dan      users           0 May 29 12:07 asdf.sig
    -rw-r--r--   1 dan      users           0 May 29 12:06 asdfasdfasdf.d
    -rw-r--r--   1 dan      users           0 May 29 12:06 asdfasdfasdf.sig
    -rw-r--r--   1 dan      users         158 May 29 12:09 makefile

    >> make
    making asdf.oo

    >> ls -l make.exe
    -rwxr-xr-x   1 dan      users      150016 Feb  5 02:11 make.exe

    >> make -v

I wonder whether this is related to the bug (feature?) that identifies the
file asdfasdfasdf.d with the truncated name asdfasdf.d.  What I mean is
that with the files above, the command 'cat asdfasdf.d' will work,
unfortunately and ambiguously, taking the first file it finds with those 8
letter in its name.
