failure in test No. 503

[Armin Faltl]

Hi,

when compiling and checking autoconf on Centos 7.2.1511 server
with gcc-5.4.0 and Perl-5.24.0 installed in the /usr/local tree,
I ran into an error in the 'autoscan'-script.

As you can see from the attachment, I attempted a fix, that
creates a valid regular expression and passes the 'make check'
and 'make installcheck' tests.

Since the patterns around there contain no variables, I added
the flag 'o' to the regex, to speed up the script.

Regards, Armin
