Would you mine testing GCC6? IIRC exception handling is broken in 6,
which is why it is stuck in test.

I suppose I can put gcc 6.3 in test soon.

Woops, looks like gcc-6.3 is already in test.

Taking a closer look at the bug report, we're still using the old C++
ABI, so we're unaffected.

Jon,

are you building the compilers on cygwin or cross compiling ?

I was trying to test the patch for
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=47030
as it is blocking PETSC porting,
but I was unable to build 6.3.0-1 from your
source package.

Its libstdc++6 DLL is broken:

On Cygwin itself, shouldn't that be 32bit and 64bit respectively for Cygwin?

In theory

gcc/real.h:#define SIGNIFICAND_BITS   (128 + HOST_BITS_PER_LONG)

gcc/hwint.h:#define HOST_BITS_PER_LONG  (CHAR_BIT * SIZEOF_LONG)


but I do not understand why SIGSZ is wrong defined.

FWIW, I just rebuilt gcc-6.3.0-1 from source on 64-bit Cygwin without 
getting that warning.

It helps to focus on my PC installation

Good news, I don't see the duplicate addresses anymore after the
binutils update (hopefully I am not reading objdump wrong), however the
slow nm problem which I thought was fixed is still there.

Uploading new gcc soon.

Now that the issue with readline has been resolved, thanks to great work by
Corinna and Eric, I wanted to revist some other of my issues. I am reposting
this because it is a new month.

Some work was done on this in June and July, but I still do not see even a test
version with the mingw64-*-gcc-* packages. I use Cygwin quite a bit, but when I
can I prefer to build Windows native versions of programs, this way I can share
them without worrying about the Cygwin DLL.

Can we please release at least test versions of the mingw64-*-gcc-* packages?

Sure, I'll start bringing up mingw-w64 6.x within the week.
