Is there a portable way to implement _mm_malloc?

Sure. Allocate ALIGN bytes more than needed, clear the first ALIGN bytes, mark
the first byte with 1, and round up to proper alignment. On freeing you can then
scan back to the mark byte.

Isn't posix_memalign() portable enough ?

No posix_memalign is not potable enough as Windows does not provide it.

Hi,
A version of _aligned_malloc and friends was submitted to mingw project and
declared as public domain. I have been using it for some time with no problem.
It works on i686 linux and mingw. You may want to look at it for a portable
implemtation that could be used as mm_malloc. It would also be useful for an
overloaded (aligned) new/delete implementation

I think we should have 2 versions. One uses posix_memalign and the other one
doesn't. A target can pick the best one.

Agreed.
As for the "other one", I like the _aligned_malloc implementation posted by
Danny, even though it's using more memory (from 32 to 64 bits) than the marker idea.
