dnl major rewriting for Tcl 7.5 by Don Libes <libes@nist.gov>

dnl gdb/configure.in uses BFD_NEED_DECLARATION, so get its definition.

sinclude(../bfd/bfd.m4)

dnl This gets the standard macros, like the TCL, TK, etc ones.

sinclude(../config/acinclude.m4)

dnl This gets GCC_HEADER_STDINT.

sinclude(../config/gettext-sister.m4)

dnl For AC_LIB_HAVE_LINKFLAGS.

#  - Acceptable Tcl major version #s is 7-9 while Tk is 4-9

#  - Searching for Tcl includes looking for tclInt.h, Tk looks for tk.h

#  - Computing major/minor versions is different because Tk depends on
