Well - the date is always much newer than the other source files in
Which of the Makefiles should I comment the reference out in? I see a
section in ./src/gmxlib/Makefile which lists:
Of course each time I re-run configure this is wiped out. Can I change
this semi-permanently by modifying the similar section in
src/gmxlib/Makefile.am or .in ?
