Package: libc6-dev
Version: 2.3.2.ds1-20
The following program fails to compile, using gcc version 3.3.5 (Debian
1:3.3.5-8) using the noted flags:
// Compiling this g++ -c -pedantic -ffast-math -O gives errors due to an
// ?: operator in bits/mathinline.h.
#include <math.h>
The problem is a ?: operator that occurs in <bits/mathinline.h>. I
enclose a patch that fixes the bug.
Here are the compile error messages:
$ g++ -c -pedantic -ffast-math -O2 t.cc
