+ 
+       testsuite: be more cross-compile friendly
+       * tests/defs.in (cross_compiling): New subroutine.
+       (am__tool_prefix): New internal variable.
+       (gcc, g++, gcj): Force the use of the correct "tool prefix"
+       when cross compiling.
+       (gfortran, g77, non-cross): New requirements.

+       tests: fix portability issues in 'repeated-options.test'
+       * tests/repeated-options.test: Do not assume that object files
+       have `.o' suffix and executables have no default suffix; instead,
+       use `$(OBJEXT)' and `$(EXEEXT)'.

 +
 +      tests: fix spurious failure of extradep.test on FreeBSD
 +      * tests/extradep.test: When using `ls -t' to determine whether a
 +      file has been updated, make sure to use as reference a file whose
 +      timestamp is expected to be *strictly* older that that of the file
 +      being checked.  This is required because at least FreeBSD `ls' do
 +      not sort files with the same timestamp in alphabetical order when
 +      using the `-t' option.
 +      * tests/extradep2.test: Likewise.
