Hello there,
the bootstrap script contains a hardcoded call to 'sh',
which renders the self-bootstraping unusable on FreeBSD
and DragonFlyBSD. The reason is that the default Bourne
shell on these systems handles the crucial invocation
$ /bin/sh -c 'echo "$1 --> $2"' -- old new
new -->
by removing the placeholder '--' despite the switch '-c'.
This is a different behaviour from all other '/bin/sh'
tested by me, including GNU/Linux, other BSDm and multiple
shells on OpenSolaris.
The patch given below, will improve the situation to allow
$ CONFIG_SHELL=/usr/local/bin/mksh ./bootstrap
with FreeBSD and DragonFlyBSD in a typical source
directory, like GNU Inetutils.
Best regards,
Mats Erik Andersson, working for GNU Inetutils.
