Subject: [PATCH] Ignore _unaligned and __unaligned. Required >15years ago, but
 still present in old code

These extensions where used by other compiler
to generate different code on old cpu's (arm and x86 before pentium/pentiumpro)
to prevent processor exceptions / very high delays when accessing an unaligned pointer.
