[Bug binutils/11711] New: directory names conflict with windres include directories

[anthony dot penniston at hotmail dot com]

When specifying include directories for windres via the "-I" or "--include-dir="
options that also happen to match input formats (i.e. a directory named "res"),
windres assumes they are the latter and outputs a warning. This obscure
backwards-compatibility reference causes confusion and is only briefly mentioned
in the windres manual which still does not explain the following problems:

1) The warning is emitted even if including a -J option which explicitly
specifies the input format. I.E. "windres -J res -I res" should make it obvious
that the -I option refers to an input directory and not an input format.

2) Using the "--include-dir=" should also make it explicit that
"--include-dir=res" is specifying an include dir named "res" and not an input
format.

3) Quoting the the input directory as in "-I "res"" should also make it explicit
that a directory is being provided rather than an input format.

4) Any gains in backwards-compat. surely out-weigh those lost in forwards- and
cross-compatibility (i.e. see the "/I" option in RC:
http://msdn.microsoft.com/en-us/library/aa381055%28VS.85%29.aspx)

If it's the case that backwards-compat. trumps all, then in the least, problem
#2 should be fixed (i.e. "--include-dir=res" should include directory "res").
Another developer from the mailing list has notified that he has a patch ready
to address this issue.
