Because some architectures are very, very special.
* configure.ac (cc_flags_m32, cc_flags_mx32): New variables. AC_SUBST
them.
* m4/mpers.m4 (MPERS_CFLAGS): Use instead of CFLAG, pushdef as
$cc_flags_$1.
Use mpers_name instead of CFLAG in AC_CACHE_CHECK messages.
Pass MPERS_CFLAGS as the second argument to mpers_test.sh
* mpers.sh: Add CC_ARCH_FLAGS as the second argument (PARSER_FILE
is moved to the third one). Do not expect leading dash in ARCH_FLAG
anymore.
* mpers_test.sh (mpers_cc_flags): New variable, initialise to the second
command line argument.
Pass $mpers_name without leading dash to mpers.sh.
Pass $mpers_cc_flags as the second argument to mpers.sh ($sample is
the third argument now).
* Makefile.am (mpers-m%.stamp:): Pass $(mpers_CC_FLAGS) as the second
argument to mpers.sh ($$f is now the third argument).
($(mpers_m32_targets)): Define target variable mpers_CC_FLAGS with the
value of @cc_flags_m32@
($(mpers_mx32_targets)): Define target variable mpers_CC_FLAGS with the
value of @cc_flags_mx32@
* tests/Makefile.am (MERS_CC_FLAGS): New variable.
* bootstrap: Append @cc_flags_$1@ to MPERS_CC_FLAGS. Append
$(MPERS_CC_FLAGS) to ARCH_MFLAGS.
* configure.ac [$arch = mips]: Use AC_MSG_FAILURE instead of
AC_MSG_ERROR when _MIPS_SIM cannot be determined. Use AC_MSG_ERROR
instead of AC_MSG_FAILURE when syscallent stubs cannot be generated.
On architectures supporting multiple personalities, multiple
personalities support in strace is required for proper decoding of
structures used by tracees with personalities that differ from the
personality of strace.
New configure options control whether multiple personalities support
in strace is mandatory, optional, or disabled.
The default is changed from what is now equivalent of
--enable-mpers=check (automatically detect whether required mpers
support could be enabled) to --enable-mpers (terminate the build
if required mpers support could not be enabled).
* configure.ac (AC_ARG_ENABLE([mpers])): New option.
* m4/mpers.m4 (st_MPERS): Use enable_mpers. Terminate the build
if mpers could not be enabled and enable_mpers==yes.
* strace.spec.in: Specify --enable-mpers=check to %configure.
* debian/rules (build/Makefile, build64/Makefile): Specify
--enable-mpers=check to configure.

When using linux kernel headers without commit v4.5-rc1~128^2~115^2~22

internal definitions and definitions present in the system headers.
