RE: libstdc++ installation questions.

Hi,

     I tried to install libstdc++ again today. Instead of specifying a
directory on
the --prefix=some_directory, I just use --prefix=./ when I run the configure
script.
And I got the following errors:


gmake
gmake  all-recursive

Making all in math
gmake[2]: Entering directory `/pri_software/gnu/bld-libstdc++/math'

Maybe...

Cursiously I can't reproduce the  reported behaviour.  Can you?

It's important we get this one right...
