section 9.1:

If file does not exist, is a directory, or cannot otherwise be read, the expansion is void, and include will fail with an error while sinclude is silent. The empty string counts as a file that does not exist.
What part of "is silent" does the version of M4 that comes with RHL4  
not understand?  What does "m4 --version" print on your RHL4 system?
(It works on my Mac OS X 10.5.x system, with GNU M4 1.4.6, even  
without plugins/Custom.m4; presumably the intent is to allow somebody  
to create a Custom.m4 file if they need it for a plugin, and have it  
be included if it's present, without *requiring* it to be there.)
