Cross build of newlib-cygwin release tag cygwin-2_11_1-release.




I'm trying to cross build the Cygwin source on a VirtualBox Arch Linux
with GCC-7.3.0 and Binutils 2.31. The process I am using clones the
master repository and then does a checkout of the release tag.  Here is
the configure command from the head of the config.log.

```
$ head /home/cygsimple/src/sf/build/newlib-cygwin/build/config.log |
grep newlib-cygwin-2.11.1/configure
$
/home/cygsimple/src/sf/build/newlib-cygwin/src/newlib-cygwin-2.11.1/configure
--prefix=/usr --host=x86_64-pc-cygwin --build=x86_64-pc-linux-gnu
--target=x86_64-pc-cygwin --sysconfdir=/etc --sharedstatedir=/var
--localstatedir=/var
```

With this I get the following errors when compiling _cygwin_crt0_common.cc:

```
c++wrap -pedantic -fomit-frame-pointer -m64 -O2 -g -fno-rtti
-fno-exceptions -fno-use-cxa-atexit -Wall -Wstrict-aliasing
-Wwrite-strings -fno-common -pipe -fbuiltin -fmessage-length=0 -MMD
-Werror -fmerge-constants -ftracer -mcmodel=small -std=gnu++98 -c -o
_cygwin_crt0_common.o

```

It appears that c++wrap isn't choosing the correct compiler but how can
I tell and change that?
