I won't help you for your configure script, but I just want to mention
that I had many problem with maui compiled by GCC 4. I had to went back
to GCC 3 in order to have a proper build of maui.
The reason is that maui use sprintf with overlapping memory acces : the
use of sprintf() to append to a buffer, as in sprintf(buf, "%sEntry:
%d\n", buf, i) is not valid according to C99 ("If copying takes place
between objects that overlap, the behavior is undefined.") which can
result to undefined result according to C standard.
And GCC4 seems to handle that differently than GCC3.
