gcc-5.3.0-1 has been uploaded for 32bit and 64bit Cygwin.

GCC5 uses a new versioning scheme, under the old scheme, it would be
5.0.3, with 5.2.0 as 5.0.2. See https://gcc.gnu.org/develop.html under
"Version Numbering Scheme for GCC 5 and Up".

This version has been built with
--with-default-libstdcxx-abi=gcc4-compatible so it should remain
compatible to GCC 4 C++ ABI.

Note that C11 with gnu extensions is now default for C. See
https://gcc.gnu.org/gcc-5/porting_to.html for more help on porting code
to GCC 5.

Jon,

A few issues so far with this version:

* the -rdynamic flag still isn't recognized;

* the libgomp plugin loader is using the wrong library names;

* the libstdc++ gdb/python scripts need to be rearranged.

A merged and fixed patch 0011, a new patch 0022, and the necessary fixes 
to the .cygport can be found here:

https://github.com/cygwinports/gcc/commit/3a4ccda91fdddf766696d0fdf2efda1e6881b34e

Can you spin a 5.3.0-2 with these changes?

Update: I added a patch 0023 to enable _GLIBCXX_USE_C99, which enables 
std::stod, std::to_string, etc.  However, some newlib headers need to be 
fixed, so let me get those in first.

Jon,

I have added several other improvements:

https://github.com/cygwinports/gcc/

In addition to the aforementioned changes, these patches allow enabling 
_GLIBCXX_USE_C99 with cygwin-devel-2.4.1 (but see below), as well as 
enabling libitm and cilkplus.

If you could, applying the following fix to your /usr/include/ieeefp.h 
before building will help a bit as well:

https://sourceware.org/git/?p=newlib-cygwin.git;a=commitdiff;h=ac2f9e23ecd197758e7cc2ca1b8717add3d8762b;hp=8b8952064cfacf91b18aed37fbd44f621edb6941

I believe a 5.3.0-2 with all those changes should be ready for stable.
