  The @code{c-strcasestr} module contains a case-insensitive string search
  function operating on single-byte character strings, that operate as if the
  locale encoding was ASCII.
  (The "C" locale on many systems has the locale encoding "ASCII".)
  
  The function is:
  @smallexample
  extern char *c_strcasestr (const char *haystack, const char *needle);
  @end smallexample
  
  For case conversion here, only ASCII characters are considered to be
  upper case or lower case.
  
  Note: The function @code{strcasestr} from @code{<string.h>} supports only
  unibyte locales; for multibyte locales, you need the function
  @code{mbscasestr}.
