[PATCH 0 of 5] Several patches for OSX,uClibc,gdb-6.8

[Titus von Boxberg]

Yann, all,

this patch series corrects various bugs when building on OSX.
It cares about the bugs recently reported by Guylhem Aznar
and Pierrick Brossin building cloog/ppl, uClibc (0.9.30), and gdb (6.8).

Regards
Titus

configure: correct check_for

check_for didn't set variable 'where' when the path to a prog
was passed manually "(cached)".

[PATCH 2 of 5] main: need path to libtoolize

main: need path to libtoolize

libtoolize must be checked_for and there needs to be a wrapper
that points to GNU libtoolize since that may be installed
as glibtoolize.

[PATCH 4 of 5] docs/Using on MacOS: Document usage with Xcode 4.1

docs/Using on MacOS: Document usage with Xcode 4.1

With Xcode 4.1 'gcc' is symlinked llvm-gcc-4.2 which cannot bootstrap
other gccs.
See http://llvm.org/bugs/show_bug.cgi?id=9571

On my machine the faulty gcc is
gcc version 4.2.1 (Based on Apple Inc. build 5658) (LLVM build 2335.15.00)

Document a workaround.

patches/gdb/6.8: correct compilation error when stpcpy is a define

On OSX stpcpy is a define which is not recognized by gdb's configure.
This results in a compilation error.

Care to resubmit, adding Reported-by: tags as appropriate, please?

The order is:
  Reported-by: John Doe <john@doe.net>
  Tested-by: "Random J. Tester" <r.j@tester.net>
  Signed-off-by: Jane Doe <jane@doe.net>

If multiple reporters, try listing first reporter firts. If possible,
it is not really important; what is important is that people get credited
for the job they did. And reporters are important too. ;-)

Thank you!

Yann E. MORIN.

Also, could you recategorise the changesets:

patch 1/5:   configure: fix --with-prog=[...]
patch 2/5:   configure: require libtoolise, create wrapper
patch 3/5:   libc/uClibc: portability fixes to install_headers
patch 4/5:   docs: document usage with Xcode 4.1
patch 5/5:   debug/gdb: correct compilation error when stpcpy is a define

The global rule is:

 - when changing a component, the prefix is: categroy/component
   for example:
      kernel/linux: add blabla
      arch/arm: do foo bar
      debug/gdb: buzify the bazel
      libc/uClibc: check the stuff
      complibs/ppl: do that foolish stuff again

 - when changing configure (and the correspondiong stuff in Makefile.in)
   the prefix is simply: configure
   for example:
      configure: fix blabla, require foobar

 - when changing stuff in kconfig, the prefix should be: kconfig
   optionally, the frontend can be specified. eg.:
      kconfig: fix bla bla
      kconfig/mconf: show bar buz
      kconfig/nconf: hide bar buz

 - other prefixes could be:
      config   : for changes to the infrastructure in the config/ dir
      scripts  : for changes to the infrastructure in the scripts/ dir
      samples  : for changes in the samples/ dir
      docs     : for changes to the documentation

Deviations to the rule can apply, of course, but that should be the exception
rather than the rule.

No, this is not documented, I'll do it soon (probably tomorrow).

Thanks again for looking into that! :-)

Yann E. MORIN.
