egcs/ChangeLog:
1998-06-26  Manfred Hollstein  <manfred@s-direktnet.de>
* Makefile.in (BASE_FLAGS_TO_PASS): Add gcc_version_trigger.
(Makefile): Depend on $(gcc_version_trigger).
* configure (gcc_version): Change default initializer to empty
string.
(gcc_version_trigger): New variable; pass this variable down
to subdir configures to enable them checking gcc's version
themselves. Emit make macros for both gcc_version vars.
(topsrcdir): Initialize reliably.
(recursion line): Remove --with-gcc-version=${gcc_version}.
egcs/gcc/ChangeLog:
1998-06-26  Manfred Hollstein  <manfred@s-direktnet.de>
* Makefile.in (gcc_version, gcc_version_trigger): New macros.
(version): Initialize from $(gcc_version).
* configure.in (version): Rename to gcc_version.
(gcc_version_trigger): New variable; call AC_SUBST for it and
emit it into the generated config.status.
* configure: Regenerate.
egcs/libf2c/ChangeLog.egcs:
1998-06-26  Manfred Hollstein  <manfred@s-direktnet.de>
* Makefile.in (gcc_version_trigger): Add new macro.
(config.status): Add dependency upon $(gcc_version_trigger).
* configure.in (gcc_version_trigger): New variable; initialize
using value from toplevel configure; add AC_SUBST for it.
(gcc_version): Change initialization to use this new variable.
* configure: Regenerate.
egcs/libio/ChangeLog:
1998-06-26  Manfred Hollstein  <manfred@s-direktnet.de>
* config.shared (FLAGS_TO_PASS): Add gcc_version_trigger.
(Makefile): Add dependency upon $(gcc_version_trigger).
