# Skip the current test if valgrind doesn't work,

# or hasn't support for the built architecture,
# or hasn't appropriate error suppressions installed etc.

# This goes hand in hand with the "exec 9>&2;" in tests/Makefile.am's
# TESTS_ENVIRONMENT definition.

# Having an unsearchable directory in PATH causes execve to fail with EACCES
# when applied to an unresolvable program name, contrary to the desired ENOENT.
# Avoid the problem by rewriting PATH to exclude unsearchable directories.
# Also, if PATH lacks /sbin and/or /usr/sbin, append it/them.
