From 57a5a0095c3fe0f22dcbb9d99a82cc94f2b608c7 Mon Sep 17 00:00:00 2001 From: Russ Allbery Date: Sun, 17 Jan 2016 14:30:53 -0800 Subject: Update to rra-c-util 5.10 and C TAP Harness 3.4 Update to rra-c-util 5.10: * Add missing va_end to xasprintf implementation. * Fix Perl test suite framework for new Automake relative paths. * Improve portability to Kerberos included in Solaris 10. * Use appropriate warning flags with Clang (currently not warning clean). Update to C TAP Harness 3.4: * Fix segfault in runtests with an empty test list. * Display verbose test results with -v or C_TAP_VERBOSE. * Test infrastructure builds cleanly with Clang warnings. * Support comments and blank lines in test lists. --- m4/clang.m4 | 26 ++++++++++++++++++++++++++ m4/krb5.m4 | 40 +++++++++++++++++++++++++--------------- 2 files changed, 51 insertions(+), 15 deletions(-) create mode 100644 m4/clang.m4 (limited to 'm4') diff --git a/m4/clang.m4 b/m4/clang.m4 new file mode 100644 index 0000000..0659d82 --- /dev/null +++ b/m4/clang.m4 @@ -0,0 +1,26 @@ +dnl Determine whether the current compiler is Clang. +dnl +dnl If the current compiler is Clang, set the shell variable CLANG to yes. +dnl +dnl The canonical version of this file is maintained in the rra-c-util +dnl package, available at . +dnl +dnl Copyright 2015 Russ Allbery +dnl +dnl This file is free software; the authors give unlimited permission to copy +dnl and/or distribute it, with or without modifications, as long as this +dnl notice is preserved. + +dnl Source used by RRA_PROG_CC_CLANG. +AC_DEFUN([_RRA_PROG_CC_CLANG_SOURCE], [[ +#if ! __clang__ +#error +#endif +]]) + +AC_DEFUN([RRA_PROG_CC_CLANG], +[AC_CACHE_CHECK([if the compiler is Clang], [rra_cv_prog_cc_clang], + [AC_COMPILE_IFELSE([AC_LANG_SOURCE([_RRA_PROG_CC_CLANG_SOURCE])], + [rra_cv_prog_cc_clang=yes], + [rra_cv_prog_cc_clang=no])]) + AS_IF([test x"$rra_cv_prog_cc_clang" = xyes], [CLANG=yes])]) diff --git a/m4/krb5.m4 b/m4/krb5.m4 index 79ef961..683e30b 100644 --- a/m4/krb5.m4 +++ b/m4/krb5.m4 @@ -64,6 +64,8 @@ dnl Headers to include when probing for Kerberos library properties.
