Description:
Memory allocation on the stack, as an optional optimization.
It allows using the alloca() macro if and only if the autoconf tests define
HAVE_ALLOCA.

lib/alloca.in.h
m4/alloca.m4

Depends-on:

configure.ac:
gl_FUNC_ALLOCA

Makefile.am:
BUILT_SOURCES += $(ALLOCA_H)

# We need the following in order to create <alloca.h> when the system
# doesn't have one that works with the given compiler.
