# ignore-cross-compile -- compiling C++ code does not work well when cross-compiling

# This test case makes sure that native libraries are linked with appropriate semantics
# when the `[+-]bundle,[+-]whole-archive` modifiers are applied to them.
#
# The test works by checking that the resulting executables produce the expected output,
# part of which is emitted by otherwise unreferenced C code. If +whole-archive didn't work
# that code would never make it into the final executable and we'd thus be missing some
# of the output.
