As Havoc said, this is almost certainly a 2.2 feature at this time.

But also, these type of functions are a pain to implement portably,
even more so than alloca itself, ... you can't return alloca memory
from a function call, and statement expressions (what the glibc
g_strdupa() uses) are a GCC extension. An alloca g_strdup_printf() is
probably impossible. The others, are feasible at some cost in efficiency.
