This statement causes a warning with autoconf-2.49a:
configure.in:559: warning: backquotes and double quotes should not be
backslashed in: configure:__oline__: checking extra library \"$i\"
Probably harmless but not nice.
The best solution I was able to find that produces no warnings both with
2.13 and 2.49a is:
q='"'
AC_MSG_CHECKING(extra library $q$i$q)
But it's quite ugly too.
