dnl written by Rob Savoye <rob@cygnus.com> for Cygnus Support
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/stdint.m4)

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

dnl For AC_LIB_HAVE_LINKFLAGS.
sinclude(../config/lib-ld.m4)

sinclude(../config/lib-link.m4)

#
# Sometimes the native compiler is a bogus stub for gcc or /usr/ucb/cc. This
# makes configure think it's cross compiling. If --target wasn't used, then
# we can't configure, so something is wrong. We don't use the cache
# here cause if somebody fixes their compiler install, we want this to work.

# the Tk differences and later simply substitute "Tk" for "Tcl".
# Known differences:
#  - 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
#    headers to Tcl, Tk, and X.
#  - Symbols in tkConfig.sh are different than tclConfig.sh
#  - Acceptable for Tk to be missing but not Tcl.
