preprocessor: Initialize a potentially uninitialized variable.
My current reading of the relevant static functions suggests that last
is never used without being uninitialized, (we only use it if the
expansion function returned non-NULL and the expansion functions
always set it before returning non-NULL).
Apparently gcc isn't coming to the same conclusion. Initializing this
to NULL nicely quites gcc and will guarantee a nice, early segfault if
my anaylsis turns out to be wrong.

Use AH_TOP and AH_BOTTOM macros so that the standard include guard
mechanisms are emitted by autoheader into the generated config.h file.

configure: Remove some dead code.
This block of code is useless because a (nearly-equivalent) assignment
is made immediately after. The only difference is the omission of
-Wunreadchable-code in the assignment being used. Presumably, that was
intended to be -Wunreachable-code (without the first 'd'), but since
this hasn't been being used we just drop it.

Fix typos of "variable" as "varaible"
One of these was just in a comment. But ther other was in an enum
tag, (which is apparently not being used anywhere yet).
