There is no need to compile our DLLs as shared libraries since we are
managing symbols exports and imports through spec files.
On my system, this reduces the configure-time by a factor of two.
This is a temporary fix for a timeout in windowscodecs:tiffformat.
The test ends up invoking Win32ErrorHandler with:
_TIFFVSetField: <IStream object>: Bad value 0 for "ResolutionUnit" tag.
Ideally we'd keep the MessageBox version of the error/warning handlers but
make them respect the current error mode to avoid blocking tests and other
non-interactive applications.
