Exactly what problem do you experience? I have no problem executing the
above code.

In m4, trailing whitespace in arguments is relavant. The m4 manual states
that leading whitespace on arguments is discarded, but trailing whitespace is
not. Also note that the quotes [ and ] do not expressly delimit an
argument; they simply quote parts of it. With and without the brackets, the
arguments you are passing to AC_CONFIG_FILES() all contain trailing
whitespace.

Given that m4 is mainly a text processing facility, it makes sense that it
tries to preserve the format of the text.
