cxxtestgen does not warn when a file in "--headers" is missing

[mambu]

Using CxxTest Version 4.3 (2013-07-05)
Running
cxxtestgen --runner=XUnitPrinter --xunit-file=cxxtest.xml --headers=tests -w mytests --have-eh -o TestRunner.cc
with a list of files that are not present in the filesystem listed in file "tests" does not produce an error.
The exit code is 0.

Would it be possible to print something to stdout with a warning or an error saying which files are missing and return a code different than 0?

ERROR: the file 'tests' does not exist!

Here's result in 4.4. I think it's doing what you want. Or am I missing something?
