Dear Alexander Lukichev,

Looks really good now. The only thing missing I believe is a
description + Signed-off-by line in the
package/openpgm/openpgm-cross-compile.patch file.

Also, did you test this package against uClibc or glibc? If against
glibc, then you should make a test against a minimal uClibc
configuration (no thread, no largefile, no IPv6, no RPC, no wchar, no
locale), to check that your package indeed doesn't depend on any of
these uClibc features. If you don't want to build a minimal uClibc
toolchain from scratch, you may use
http://autobuild.buildroot.org/toolchains/tarballs/br-arm-basic.tar.bz2.

Best regards,

Thomas

Oops! I intended to do so but it fell out of my head. Will be fixed.

uClibc 0.9.33 only with largefile, threads and all the friends. I guess, threads are mandatory for this library. I'll set the correct dependencies and test with different base libs. Thanks.

  When you resubmit, please also:

- set the patch prefix to 'PATCH v3', using

git send-email --subject-prefix='PATCH v3' ...

- Include the changelog (which you now had in a separate mail) in the 
commit message itself, like so:

v3: Added Signed-off-by to the patch

v2: improved according to community suggestions:
- legal information supplied;
- OPENPGM_SUBDIR is used instead of a post extract hook;
- more recent release of the package is used;
- cross-compilation fix uses cached values instead of hard-coded ones.

The last thing has been implemented as recommended in Autoconf manual
(http://www.gnu.org/savannah-checkouts/gnu/autoconf/manual/autoconf-2.69/html_node/Runtime.html#Runtime)
for cross-compilation-friendly runtime tests. Direct caching of
pgm_unaligned_pointers variable produced a warning during autoreconfigure
that said that only variables containing _cv_ were cached, and
ac_cv_lbl_unaligned_fail was already used in Buildroot, so I based the
test on that one and set pgm_unaligned_pointers later from its result.
