[Message part 1 (text/plain, inline)]

I would also like to report 4 of 788 tests failed with Clang using:

    Mac OSX 10.7.3 Lion
    clang-3.1 (318)
    automake-1.11.3
    autoconf-2.68
    gawk-4.0.0


Attached are my test results.  I think I noticed some were minor things,
where the test code met unexpected arguments in my CFLAGS.  Those
are probably fixed in HEAD already, but in case they are not, here is some
background info:


Clang has some strange ways of sending flags to the linker or preprocessor.
Most people are familiar with the

    -Wl,-shared

sort of notation for gcc and the linker, but with Clang my CFLAGS
when using Homebrew contain items like these

    -w -pipe -march=native -Xclang -target-feature -Xclang -aes

Ok thanks for your help on this and my previous bug report.

Thanks for the report.

It's correct that the testsuite code in the master branch is more careful
and faithful in respecting the user choice of compilers and their flags.
In case you feel like giving it a try, that would be much appreciated (as I
cannot test on a MacOS X system myself).

And I see that, apart from the 'conffile-leading-dot.test' failure (that you
have already reported in bug#10848), all the other failures are due to GCC
getting unexpected values of CFLAGS... and this, as you've guessed, should
already be fixed in master.  So I'm closing this bug report.

In case you decide to test the master branch with Clang and run into
similar problems, feel free to open a new bug report.

Thanks again,
  Stefano
