Would you say that it is a bug that on Windows the error message is displayed in a message box instead of written to stderr?

It is something which can be changed when libtiff is compiled. At the top of nmake.opt, you can find:

#

# Select WINMODE_CONSOLE to build a library which reports errors to stderr, or # WINMODE_WINDOWED to build such that errors are reported via MessageBox().

#
WINMODE_CONSOLE = 1
#WINMODE_WINDOWED = 1

But it might be easier to install an error handler which prints the errors to stderr than to rebuild or change your libtiff.
