--enable-dwarf2 seems to work just fine on Cygwin32, except for the fact that
GDB turns up its nose at the presence of DWARF debug info in files that aren't
ELF (such as WindowsNT PE files). This problem reared its UGLY head when I was
trying to debug the built-but-not-installed GCC 4 I keep on hand. Error
messages are as follows:
