* configure: Add a check, in the case that we cannot make an

executable, whether this is due to being required to use C99.
For instance, the Solaris environment requires compilation
using the C99 dialect if _XOPEN_SOURCE is set to 600 or higher.

* debug.c: When compiling as C99, we have to obey the special
C99 conventions for instantiating inline functions.

* hash.c: Likewise.

* lib.c: Likewise.

* parser.y: Likewise.

* unwind.c: Likewise.
