where does it say that? In man sscanf? The only reference to this text
I can find is from man printf: <http://linux.die.net/man/3/printf>

To reiterate:

a    scanf glibc extension, eg FreeBSD and Solaris don't have it
m    In SUSv4 [1], but not in SUSv3 [2], supported by glibc since 2.7, FreeBSD

Looks like at least Solaris 11.1 doesn't have m yet, maybe it's in 11.2.
