Hi Peter. Since the test 't/objcxx-basic.sh' was indeed failing with autoconf 2.62, I've folded in the following diff, inspired by your patch:
diff --git a/t/objcxx-basic.sh b/t/objcxx-basic.sh index 50e1399..04a42a4 100755 --- a/t/objcxx-basic.sh +++ b/t/objcxx-basic.sh @@ -26,10 +26,21 @@ AUTOMAKE_fails grep 'OBJCXX.* undefined' stderr grep 'add .*AC_PROG_OBJCXX' stderr -echo AC_PROG_OBJCXX >> configure.ac -$ACLOCAL --force -$AUTOMAKE +cat >> configure.ac <<'END' +dnl Support for Object C++ was introduced only in Autoconf 2.65. +AC_PREREQ([2.65]) +AC_PROG_OBJCXX +END +if $ACLOCAL --force; then + : We have a modern enough autocon, go ahead +elif test $? -eq 63; then + skip_ "Object C++ support requires Autoconf 2.65 or later" +else + Exit 1 # Some other aclocal failure. +fi + +$AUTOMAKE $EGREP '^\.SUFFIXES:.* \.mm( |$)' Makefile.in : The test now works with Autoconf 2.65 and 2.69, and is correctly skipped with Autoconf 2.64 and 2.62.
