Thank you very much, Dr Case.
After implementing the changes you described, I was able
to compile AmberTools and all tests were fine. I had to
compile lmodC.c with optimization turned off, i.e -O0,
because with -O the minimum energy for the simple lmod
optimization test did not fall within -115 to -125, but
with -O0 the value turned out to be -123.
I really appreciate your kind help.
Thank you again,
Shan-Ho
