Hi Adnan,

You're speaking the wrong language.  The configure.ac file is
a mixture of m4 + Bourne shell.  Your conditionals appear to be
C preprocessing conditional code.  Anyway, it is cleaner to
define two macros and then:

  [if ${TESTING} ; then]
     MY_TESTING_M4_MACRO
  [else]
     MY_PRODUCTION_M4_MACRO
  [fi]

with all those funny '[' and ']' thingeys making it clear that
the "enclosed" text is plain shell scripting and not for the
M4 processor to figure out.

Cheers - Bruce
