Yes.  I'm generating info, HTML and PDF versions of the GNU binutils docs, with 
only the Xtensa-specific options enabled.  I also need the man pages to work. 
The assembler documentation has something like:

@smallexample
@c man begin SYNOPSIS
list of standard options
@ifset ALPHA
Alpha-specific options
@end ifset
...lots more machine-specific options
@ifset XTENSA
Xtensa-specific options
@end ifset
@c man end
@end smallexample

Another option would be to put each machine-specific section inside a separate 
@example environment, but I'm afraid that might mess up the man pages.  In the 
short term, I can hack around this specific instance of the problem, for 
example, by deleting all the other machine-specific options in my local copy of 
the file.  Obviously, that isn't a good long-term solution.  There may well be a 
number of other instances of the problem that are not quite so visible.  If you 
can eventually find a proper fix, that would be great.  I'd offer to help but I 
couldn't even figure out how those end-of-line parsing macros work.
