Untangle Win32 build errors.

  #define str*casecmp as stricmp causes reinterpretation of
  str*casecmp function declarations.  This creates dozens of
  compiler emits.  Since there is no need, the HAVE_STRCASECMP
  macros wipe out the redeclaration.

  learning curve!  Sorry for the previous nonsense docs of
  rev 1.22 - still fighting to use the editor for docs :-)
