Well,
echo 'char test[sizeof(void *) == 8 ? 1: -1];' | \
${CC} -o /dev/null > /dev/null 2>&1

is a test for 64bit pointer sizes. But depending on which types they
actually include, it is already the base alignment. It would strongly
depend on the usage. I've added an item to my TODO list to check what
Mesa is doing.

The warning about strlen is a typical sign that the actual doesn't
include string.h.
