I agree w/ Ralph that
ln -s -f A B || { rm -f B && ln -s A B; }
should have worked despite the error message from the failing "ln -s -f
A B".
So, I don't think there was a real error here - sorry.

This is due to an incomprehensibly stupid "ln" that cares about the
order of the "-s" and "-f" options:
$ rm -f b; touch a; ln -f -s a b
$ rm -f b; touch a; ln -s -f a b
Usage: ln [-f] [-s] f1
ln [-f] [-s] f1 f2
ln [-f] [-s] f1 ... fn d1
$ which ln
/usr/ucb/ln
$ uname -a
SunOS lem.lbl.gov 5.10 s10_69 sun4u sparc SUNW,Ultra-5_10
I'll fix that option order in libtool, but I don't see how it could have
caused a failed install for you, because we explicitly do
ln -s -f A B || { rm -f B && ln -s A B; }
Please also note that this ln does not do the right thing with -f -s
when the target file already exists:
$ /usr/ucb/ln -f -s a b; echo $?
ln: b: File exists
1
Generally, having /usr/ucb early in $PATH on Solaris doesn't seem ideal,
the Autoconf manual describes several issues with tools in that
directory.
Cheers, and thanks for the report,
Ralf
