[Bug c/30477] Integer Overflow detection code optimised away, -fwrapv broken

[tg at mirbsd dot org]

------- Comment #12 from tg at mirbsd dot org  2007-01-16 17:49 -------
Reopening this bug because http://gcc.gnu.org/ml/gcc/2006-12/msg00749.html
states that:
"For example, GCC itself assumes wrapv semantics internally,"

This implies that gcc2 and gcc3 cannot compile gcc correctly,
unless using -O0. Adding -fwrapv to autoconf's defaults won't
help gcc2 and gcc3 users either, without a fix for this PR.
