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?
'emerge --info' output is:
