Yes, non gnu building of AmberTools seems to have been an afterthought.
(Do any AIX's have gnu ?)
Dave should articulate the plan here.
If we go non gnu then configure_at should be made consistent
with configure_amber.

I can fix these in short order and shall do so now.
It seems that aix is not standard conforming.?
Here is what fortran expert Ron Shepard said in 2005:
The f90 namelist termination character is "/", and it can occur in any
column. The defacto standard f77 namelist terminations were "$end" or
"&end", with the first character in the second column. In the 90's
when we were using a mix of f77 and f90, a common "trick" that worked
for both types of compilers was to end the namelist data with "/&end"
with the first character in column 1. That ended namelist in f90
because of the "/" character, and it ended (most) namelist input in f77
compilers because the "/" was ignored and the "&end" was found
beginning in column 2.
These days, this should not be necessary. At least in the very near
future, there should be no need for any f77 artifacts in the codes.
