Hardly relevant.

>Description:

The /bin/sh of FreeBSD doesn't work as on other systems, or like bash.
The problem seems to be with the builtin `eval'.

>How-To-Repeat:

bash$ foo=tomte; var=foo; echo `eval echo \\$$var`
tomte
sh$ foo=tomte; var=foo; echo `eval echo \\$$var`
5578var

>Fix:
	
I don't know of any fix that is compatible with a non-flawed sh.  A fix
would be desirable if you want your users that install GCC 2.8 to avoid
problems.  Just imagine the flood of bug reports that you will get...

If you provide me with a (reasonable) fix, I will put it in to the gcc
repository in time for 2.8.
