// Now compile a file c.cpp that uses c.h and the module c; it is important
// to first load b.pcm and a.pcm before c.pcm on the command line to trigger
// the right order of module loading. This used to trigger clang to find the
// p2/p2/a.modulemap via the path c/../p2/a.modulemap, which is not the correct
// relative path from c.
