I've identified the reason why DLL don't show up: in the startup code 
(winsup/cygwin/dcrt0.cc), in dll_crt0_0(), Win32's SetErrorMode() is 
called to suppress all OS error dialogs. It's there since 1998 according 
to the changelog, so it must not bother many people... I guess it would 
be ugly to add error messages for missing DLLs all the way up from the 
low-level spawn/exec/etc.

And in it's usual nice design practice, SetErrorMode() is a global 
setting affecting all threads in the process, so changing it temporarily 
in the spawn()/exec() function could be bad.
