Hello one and all,
As of commit b66dddb56d14a4032969fe8bb92d64baa6e0362e,
winsup/cygwin/uname.cc no longer compiles with the current GCC version
installed with cygwin itself. The newly added __attribute__ is unknown
to GCC 7, and thus triggers a -Werror for unused/unknown attributes:
$ LANG=C make
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 -Werror -fmerge-constants -ftracer
-mcmodel=small -std=gnu++98 -c -o uname.o
../../../../cygwin-clean-copy/winsup/cygwin/uname.cc
../../../../cygwin-clean-copy/winsup/cygwin/uname.cc: In function 'int
uname_x(utsname*)':
../../../../cygwin-clean-copy/winsup/cygwin/uname.cc:28:58: error:
'nonstring' attribute directive ignored [-Werror=attributes]
char buf[NI_MAXHOST + 1] __attribute__ ((nonstring));
