Looks like bugfix.2 got a extra line-feed (probably from an e-mail program):
it should look like this:
*** amber.c 2001/08/02 15:02:38 7.14
--- amber.c 2002/03/08 00:23:49
***************
*** 1446,1452 ****
tTypeInfo.iHybridization = HSP3;
else {
VP0(( "atom type %s - unknown hybridization %s\n",
! sOString( oEntry2 ) ));
continue;
}
} else if ( iObjectType(oEntry2) == OINTEGERid ) {

continue;
}
} else if ( iObjectType(oEntry2) == OINTEGERid ) {
Note that the second line starting with "!" should be a complete C statment,
ending in a semicolon. (Depending on how this gets to you, that line may have
been split into two, and needs to be rejoined.)
However, it's unlikely that this is the source of your problem: bugfix.15 for
Amber 8 is more likely to help. You could try to make the changes there
"by hand" to your amber7 sources. This usually doesn't fix the problem,
but makes it easier to find out what is going on (and the error is usually in
the input pdb file, but not always).
....good luck...dac
