The `aclocal' step is skipped during `autoreconf' because aclocal.m4 is
present.
Move the current aclocal.m4 which contains local macros into the m4/
folder. With this change the aclocal.m4 will be re-created during
changes to the m4/ macro.
This is needed so the `aclocal' can fetch m4 macros from the system if
they are references in the configure script. This is a prerequisite to
use PKG_CHECK_MODULES.

configure.ac is not detecting -Wextra in compilers that implement the
option. The problem is that -Wextra implies -Wunused-parameter, and the
C excerpt used by aclocal.m4 does not use argv. Patch from pedro at
ambientworks.net, ok djm@

clang 10's -Wimplicit-fallthrough does not understand /* FALLTHROUGH */
comments and we don't use the __attribute__((fallthrough)) that it's
looking for. This has the effect of turning off -Wimplicit-fallthrough
where it does not currently help (particularly with -Werror). ok djm@

Should prevent "unsupported -Wl,-z,retpoline" warnings during linking.
ok djm@
|
|
When using clang with -ftrapv or -sanitize=integer the tests would pass
but linking would fail with "undefined reference to __mulodi4".
Explicitly test for this before enabling -trapv.

platform hardening options: include some long long int arithmatic
to detect missing support functions for -ftrapv in libgcc and
equivalents, actually test linking when -ftrapv is supplied and
set either both -pie/-fPIE or neither. feedback and ok dtucker@

and OSSH_CHECK_LDFLAG_LINK tests to give them a better chance of
detecting toolchain-related problems; ok dtucker

tests in the configure output. ok djm.

hardening flags including -fstack-protector-strong. These default to on
if the toolchain supports them, but there is a configure-time knob
(--without-hardening) to disable them if necessary. ok djm@

options, we should corresponding -W-option when trying to determine
whether it is accepted. Also includes a warning fix on the program
fragment uses (bad main() return type).

[regress/README.regress] Remove ssh-rand-helper and all its

Thanks to tim@ for testing on affected platforms.
