I have tried this, and it works:

AC_CONFIG_FILES(translit([$1], [A-Z], [a-z])-config, chmod +x translit([$1], 
[A-Z], [a-z])-config)
])

However, it does not work with automake:

address@hidden:/tmp/tmp$ automake
configure.in: 925: required file `./translit([$1.in' not found
make: *** [Makefile.in] Error 1

It seems as though automake parses configure.ac, but does not properly
expand the macros, and so gets the name of the file wrong if it is not
a literal.  I have yet to try the latest automake (I'm using 1.4-p2),
but would be interested if you could try the script.  

AC_CONFIG_FILES(foo-config, chmod +x foo-config)
in configure.ac works fine.

However, whichever you use, it complains that the file is missing.
automake should provide some mechanism of telling it that certain
files *should not* be distributed, as it doesn't seem like it was
designed to cope with .in files being generated *by* configure on
the fly.

I suppose AC_CONFIG_COMMANDS could be used instead, but it's not as
clean.  If automake had something like AM_IGNORE_FILE(), which could
be given m4 code as well as literals, that would solve the problem.
