I don't understand why you would need two configure.ac's.

Why couldn't you solve this by an --enable option?
Then you could do

options_build2=--enable-xxx
for dir in build1 build2; do
        (mkdir $dir &&
        cd $dir &&
        eval ../configure \${options_$dir} &&
        make)
done

Ok, then you cannot use @address@hidden as it is substituted in configure time.
But you can use variables assigned on the command line.
What's the problem with the following:

COMMONDEFINES = -D_GNU_SOURCE -D_REENTRANT -DLINUX \
  -DTURN_DEBUGGING_OFF $(MY_DEFINES)

and running "make" or "make MY_DEFINES=-DUINT_WORD32" to get the two
different builds?

Have a nice day,
