Subject cvs commit: apr/i18n/unix xlate.c
Date Thu, 08 Feb 2001 02:37:30 GMT
trawick     01/02/07 18:37:30

  Modified:    .        apr_common.m4 configure.in
               i18n/unix xlate.c
  Log:
  Handle the second parameter to iconv() differently, respecting that
  some systems declare it "const char **" while other systems (and current
  Single UNIX Spec.) declare it "char **".  We'll still have to add some
  hints for some platforms to avoid warnings.
