  I may be dense but I cant seem to figure out the use of #defines w/macros
and auto substitution of parameters.  I have some Uni* code Im porting (indent
actually) that uses a statement :

#define check_size(name) \
        if (e_/**/name >= l_/**/name) { \
            register nsize = l_/**/name-s_/**/name+400; \
            name/**/buf = (char *) realloc(name/**/buf, nsize); \
            e_/**/name = name/**/buf + (e_/**/name-s_/**/name) + 1; \
            l_/**/name = name/**/buf + nsize - 5; \
            s_/**/name = name/**/buf + 1; \
        }


  and then elsewhere in the main program it does a call like:

   check_size (code);

where there are variables named e_code, l_code, codebuf and s_code already
declared.  What would be the equivalent MSC 5.1 code to do this?  I tried to
remove the offending /**/ but then I get a compile error w/e_name, etc...

  Any suggestions (apart from hard code it)??
