As reported here, compiling with +CONSHELIX e.g.

./install.com gnu xlarge M +REPDSTR +ASYNC_PME +GENCOMM +CMPI +CONSHELIX

led to a compile time object name conflict--

CALL ECHEMD(ETERM(ECHDL),X,Y,Z,DX,DY,DZ,CRVEC,HDIST(I),D

Error: Name 'hdist' at (1) is an ambiguous reference to 'hdist' from module 'mmfp'
make: *** [energy.o] Error 1

The name conflict has existed since c39b1, when a change was made in the MMFP code. It can be resolved with the following source code changes; the incorrect lines are marked with a '-', and corrected lines are marked with a '+':
