Revise configure.ac

Browse Source 
Do a little cleanup of our configure script. Highlights:

* Remove macros deemed unnecessary to call [1]
* Change check for compiler to look for one that is C99 capable-
  this automatically adds the -std=gnu99 flag

[1] Noted in the autoconf NEWS file, notably entries for 2.59d
