Hi Kirill,
good to see someone enhancing winhelp!!
a few comments though about your patch

1/ you forgot to include the changes (at least) to hlpfile.h
2/ internal function definitions
> +static BOOL  HLPFILE_ReadCntFile(HLPFILE*);
> +static void  HLPFILE_FreeCnt(HLPFILE_CNT*);

I think those two functions are not correctly designed... I'd more 
likely see something like:

+static HLPFILE_CNT*  HLPFILE_ReadCntFile(const char*);
+static void  HLPFILE_FreeCnt(HLPFILE_CNT*);

this makes the two functions consistent in what they depend on (either 
both of them are passed a HLPFILE* or none of them), and also allows to 
return the newly created HLPFILE_CNT which you never store in HLPFILE
3/ don't use C++ comments in C code

A+
