/* This may indicate that a dependent DLL could not be loaded.
Typically this occurs because we removed the CWD from the
DLL search path via SetDllDirectory (see inline function
init_cygheap::set_dll_dir), and the load mechanism expects
that dlopening a DLL from the CWD allows to load dependent
DLLs from the same dir.
To continue supporting this scenario, call LoadLibraryEx
with the LOAD_WITH_ALTERED_SEARCH_PATH flag. This flag
replaces the application path with the DLL path in the DLL
search order. This functionality needs the full path to
the loaded DLL. */
