For Cygwin dlls, look at your installed lib... packages and install the related
lib...-debuginfo packages where available:
	$ apt-cyg listall lib*-debuginfo | wc
	    350    1050   12704

Many Cygwin packages have related -debuginfo packages like other distros have
-debug packages:
	$ apt-cyg listall [a-km-zA-Z]*-debuginfo | wc
	   2110    6330   76602

I am surprised at the number of supported mingw64- packages and the scarcity of
related -debuginfo packages:
	$ apt-cyg listall mingw64- | wc
	    786    2358   31654
