[gmx-users] problem with ffamber94bon.itp

[Tomas Kubar]

hi

the file ffamber94bon.itp defines the parameters as macros. some of the 
macro names contain an asterisk character (*), e.g.
#define proper_X_CT_N*_X   0.00000     0.00000     0.00000     0.00000 
    0.00000     0.00000
this makes the preprocessor issue a warning (no whitespace after macro 
name) because a macro name is not allowed to contain this character. it 
looks like this might lead to wrong macro expansion in case this 
dihedral is contained in the molecule's topology. right now, I don't 
have an idea how to fix this...
