> New module 'alignof'.
> * lib/alignof.h: New file.
> * modules/alignof: New file.
> * lib/malloca.h: Include alignof.h.
> (sa_alignof): Remove macro.
> (sa_alignment_*): Use the alignof macro.
> * modules/malloca (Depends-on): Add alignof.
the special cases for AIX cc,xlc and HP-UX cc are not right in general.
They are only right in the context of malloca.h.
I've reverted the malloca related part of that commit and applied this fix:
2009-05-12 Bruno Haible <address@hidden>
Fix alignof macro.
* lib/alignof.h (alignof): Remove special cases for AIX and HP-UX
vendor compilers that are always correct.
