commit 1d3aa2baaee0e1c2f7cc943107406241ea580c5f
Author: Ludovic Courtès <address@hidden>
Date:   Sat Sep 4 16:56:15 2010 +0200

    Update `NEWS' for 1.9.12.
    
    * NEWS: Update.

commit 722a4fb99e0be441005c65e303359d1b5885f1c4
Author: Ludovic Courtès <address@hidden>
Date:   Sat Sep 4 16:13:42 2010 +0200

    Don't say "source file is newer" when either file is inaccessible.
    
    * libguile/load.c (compiled_is_fresh): Don't emit "source file is newer"
      warning when either FULL_FILENAME or COMPILED_FILENAME could not be
      stat'd.  This is consistent with what load/compiled-file-name do.

commit abca59fea4c3652b1587f982bbf185423967bcfb
Author: Ludovic Courtès <address@hidden>
Date:   Sat Sep 4 16:07:58 2010 +0200

    Compare source/compiled file timestamps with nano-second resolution.
    
    * libguile/load.c (compiled_is_fresh): Rename `res' to
      `compiled_is_newer'.  Use `get_stat_mtime' to compare with nano-second
      resolution when available.
    
    * module/ice-9/boot-9.scm (load)[fresh-compiled-file-name]: Likewise,
      using `stat:mtimensec'.

commit 9157d901024558ca2cb2a59d21f26b7f897714cd
Author: Ludovic Courtès <address@hidden>
Date:   Sat Sep 4 15:16:35 2010 +0200

    Use Gnulib's `stat-time' module; update Gnulib.
    
    This updates Gnulib files to v0.0-4207-gc82b481.
    
    * m4/gnulib-cache.m4: Add `stat-time'.

commit fb0b64c12a40529a03c22481570a11457076b7f9
Author: Ludovic Courtès <address@hidden>
Date:   Sat Sep 4 14:38:20 2010 +0200

    Add an entertaining `procedure->pointer' test.
    
    * test-suite/tests/foreign.test ("procedure->pointer")["bijection"]: New
      test.

-              This test is not quite right, since xlc is allowed to
-              reject this program, as the initializer for xlcbug is
-              not one of the forms that C requires support for.
-              However, doing the test right would require a run-time
-              test, and that would make cross-compilation harder.
-              Let us hope that IBM fixes the xlc bug, and also adds
-              support for this kind of constant expression.  In the
-              meantime, this test will reject xlc, which is OK, since
-              our stdbool.h substitute should suffice.  We also test
-              this with GCC, where it should work, to detect more
-              quickly whether someone messes up the test in the
-              future.  */
