* win/configure: Regen.
* win/tcl.m4 (SC_CONFIG_CFLAGS): When building with
gcc, don't attempt to link with LD or support dllwrap.
Simply require a recent version of Cygwin gcc or Mingw
gcc that supports -shared. When linking, use gcc instead
of ld since gcc automatically includes libs like -lmsvcrt.
