The new patch in itself makes the bootrapping successful without further
changes to configure.ac of Inetutils. That being said, I inserted the macro
AC_PROG_EGREP as recently as January 11th. And immediately it discloses
my ignorance of many details, sigh!

In contrast, our AC_ISC_POSIX sits fixed since 2005, but does not interfere
visibly (beyond the error log copied last time) with the advent of your most
recent change. Nonetheless, I will move it to a position where other
libraries are probed. Thank you for your most illuminating comments!

Regards,

   Mats E A
