Here's what "nm -A" tells me:

  C/.libs/ctexi2any.exe:00409fca T _rpl_getopt
  C/.libs/ctexi2any.exe:00409f4d T _rpl_getopt_internal
  C/.libs/ctexi2any.exe:00408e08 T _rpl_getopt_long
  C/.libs/ctexi2any.exe:00408e00 T _rpl_malloc
  C/.libs/ctexi2any.exe:00409020 t _rpl_mkdir
  C/.libs/ctexi2any.exe:00401410 t _rpl_mkdir
  C/.libs/ctexi2any.exe:00413114 B _rpl_optarg
  C/.libs/ctexi2any.exe:0040d664 D _rpl_opterr
  C/.libs/ctexi2any.exe:0040d660 D _rpl_optind
  C/.libs/ctexi2any.exe:0040d668 D _rpl_optopt

  C/.libs/libtexinfo-main-0.dll:62dc56d4 t __getopt_initialize
  C/.libs/libtexinfo-main-0.dll:62dc577c T __getopt_internal_r
  C/.libs/libtexinfo-main-0.dll:62dc6050 T __getopt_long_only_r
  C/.libs/libtexinfo-main-0.dll:62dc5fcb T __getopt_long_r
  C/.libs/libtexinfo-main-0.dll:62e16af8 B _rpl_optarg
  C/.libs/libtexinfo-main-0.dll:62dd9008 D _rpl_opterr
  C/.libs/libtexinfo-main-0.dll:62dd9004 D _rpl_optind
  C/.libs/libtexinfo-main-0.dll:62dd900c D _rpl_optopt
  C/.libs/libtexinfo-main-0.dll:62dc5f4a T _rpl_getopt
  C/.libs/libtexinfo-main-0.dll:62dc5ecd T _rpl_getopt_internal
  C/.libs/libtexinfo-main-0.dll:62dc5f8c T _rpl_getopt_long
  C/.libs/libtexinfo-main-0.dll:62dc6011 T _rpl_getopt_long_only

Does this mean there are actually two copies of getopt_long and its
subroutines?  If so, why did that happen?
