[which] behaves unexpected

[andreasf]

The exit code of which is not inline with the expectations of some ./autogen.sh and similar scripts.

which someexistingtool || echo "You need someexitingtool >= 0.2"

is expected to print the message iff someexistingtool is not found. On Haiku it is sometimes inversed.

Not quite fixed yet...

When running from the Terminal it appears to work as expected now, but not from inside a script:

cat test-which.sh:

#!/bin/sh
which gcc || echo $?

which gcc || echo $?:

/boot/develop/tools/gnupro/bin/gcc

./test-which.sh:

./test-which.sh: line 2: which: command not found
