Configure fails to handle aliases
Comment:
REFEREE REPORT:
1. It does not fail is rm is an alias. It gives the original executable
with an exact path.
{{{
teragon-2:sympow-1.018.1.p5 wstein$ alias rm="rm -i"
teragon-2:sympow-1.018.1.p5 wstein$ which rm
/bin/rm
teragon-2:sympow-1.018.1.p5 wstein$ RM=`which rm`
teragon-2:sympow-1.018.1.p5 wstein$ echo $RM
/bin/rm
}}}
So I totally don't get what the problem is. The above patch would have
the effect of making it so the scripts would annoyingly suddenly actually
*be* interactive if one has aliased rm to "rm -i".
So from my point of view, it looks like this patch introduces a bug
instead of fixing one.
2. This patch would replace all the absolute paths to programs to their
names, thus completely removing whatever "upstream's" point was in having
those variables. That's suspicious.
So I'm dubious.
