Bugzilla Bug 184200

Trying to install non-in-portage app (it is sci-electronics/pcb, but from CVS
tree), have got the error:

______________
...
checking for m4... /usr/bin/m4
checking if /usr/bin/m4 has the division involving negative numbers bug... yes
configure: error: It appears that /usr/bin/m4 has a bug involving division
with negative numbers.  In particular it just returned the result that
-2/2 = 2147483647 instead of -1.  This is a known bug in GNU m4-1.4.9.  Please
install a non-broken m4.
...
_______________

OTOH, this m4 version is 'stable' in portage. Is it worth to mark 1.4.9 as
'unstable', or have I missed something?

you forgot `emerge --info`

also, post information on how to reproduce this issue over here

'emerge --info' output is:
