Hi,
I'm trying to build the 3.1.7 tagged newlib. It runs into this problem:
c++wrap -O2 -g -fno-rtti -fno-exceptions -fno-use-cxa-atexit -Wall
-Wstrict-aliasing -Wwrite-strings -fno-common -pipe -fbuiltin
-fmessage-length=0 -MMD -Wimplicit-fallthrough=5 -Werror
-fmerge-constants -ftracer -c -o _cygwin_crt0_common.o
../../.././winsup/cygwin/lib/_cygwin_crt0_common.cc

This looks like a clash between the installed toolchain header and the
one in the winsup tree?
Is this a known problem?
Maybe I shouldn't be using the native Cygwin compiler for rebuilding the
Cygwin DLL; what is the right way?
