I fixed these by (a) commenting out the declaration of atexit in
aecc.h:61, and (b) using a macro for min:  ( I tried with templates,
but this is much messier than it at first appears ).

#define min(a,b) ((a) < (b) ? (a) : (b) )

(actually I used the GNU min operator, <?, which I think is nifty).

You may have to make other changes, too.  I had problems with libg++
in combination with aewindows, because aewindows defines OK as 0, which
causes problems with most of the libg++ classes, which have an OK()
member function which suddenly is " 0 () ".
