The problem is with a GCC register optimization bug similar to that found
on Berkeley C compilers ala SunOS 4.1.2.
Recode the Xt routines that have lvalues assigned to a function of
themselves where the variable in question is either a register or is
promoted to one.
Alternately, turn off optimization, add "x++; x--;" for every variable "x"
used this way in a function, declare it static, declare it volatile, or
declare it right before the function instead of in the scope of the
function.
Once the Xt library was fixed, I had no problems getting Motif 1.2 to
work.
