bug in PG_VERSION_NUM patch - Mailing list pgsql-hackers

cvs tip configure is giving a warning:

checking for flags to link embedded Perl...
/usr/lib64/perl5/5.8.6/x86_64-linux-thread-multi/auto/DynaLoader/DynaLoader.a
-L/usr/lib64/perl5/5.8.6/x86_64-linux-thread-multi/CORE-lperl -lresolv -lnsl -ldl -lm -lcrypt -lutil -lpthread -lc
 
gawk: warning: escape sequence `\.' treated as plain `.'
checking for library containing setproctitle... no

Evidently gawk is not happy about

$AWK -F'\.' '{printf \"%d%02d%02d\", $1, $2, (NF >= 3) ? $3 : 0}'`"
