Bootstrap failure [trunk]

[Angelo Graziosi]

Current rev. 100972 fails to bootstrap (on Kubuntu 10.04, for example):

=========================================

Since, rev.100971 bootstraps and works fine, and the only changes to 
rev.100972 regard 'sysdep.c', I would say that this is the culprit:
