   INI file reader

   Modification history:

   18-Dec-1997  FMP split out C code into _inifile.c
   7-Nov-1997  FMP fixed bug in afterequal so that it terminates at a 0
   25-Jul-1996  FMP added find_section() and ::section()
   11-Jul-1996  Fred Proctor made sure ini_find() returned NULL if a
   section were provided and no match was detected when the section
   was left; fixed bug which required the last line to have a newline
