--- Comment #9 from R Copley ---
For information, this has already been entered on the mingw-w64 issue tracker
(months ago) (see http://sourceforge.net/p/mingw-w64/bugs/459/).

Thanks. I've emailed the mingw-w64 list at
http://sourceforge.net/p/mingw-w64/mailman/mingw-w64-public. (You expressed it
better but I hadn't seen your last comment.)

The difference will probably be that when including libstdc++'s this
happens before mingw's is included:
// Make sure that POSIX printf/scanf functions are activated. As
// libstdc++ depends on POSIX-de

That's what I understood to be the case. Nevertheless, with the toolchain I am
using (see above for version; same command-line etc.), I get the results below.
Both testcases below give the correct results with g

--- Comment #3 from Jonathan Wakely ---
Libstdc++ has no implementation of printf, so ::printf and std::printf are
exactly the same function, with std::printf defined as:
namespace std
{
using ::printf;
}

--- Comment #2 from R Copley ---
Thanks Jonathan. It's clear enough from what I wrote that:
(1) The same kind of incorrect output is produced by (a) including and
using std::printf, and (b) using iostreams and std::hexfloat;
(2) The correct ou

Your preprocessed source doesn't use std::hexfloat, so any problem comes from
std::printf, which is part of your C library not part of GCC.
