2N/Adnl AC_LIB_ARG_WITH is synonymous to AC_ARG_WITH in autoconf-2.13, and
2N/Adnl similar to AC_ARG_WITH in autoconf 2.52...2.57 except that is doesn't
2N/Adnl require excessive bracketing.

2N/Adnl AC_LIB_PREFIX adds to the CPPFLAGS and LDFLAGS the flags that are needed
2N/Adnl to access previously installed libraries. The basic assumption is that
2N/Adnl a user will want packages to use other packages he previously installed
2N/Adnl with the same --prefix option.
2N/Adnl This macro is not needed if only AC_LIB_LINKFLAGS is used to locate
2N/Adnl libraries, but is otherwise very convenient.

2N/A dnl directory whose absolute pathname ends in /lib64, we assume a 64-bit ABI.
