[Bug libstdc++/81797] gcc 7.1.0 fails to build on macOS 10.13 (High Sierra):


https://gcc.gnu.org/bugzilla/show_bug.cgi?id=81797

(In reply to Jack Howarth from comment #9)

No, I can reproduce this with a build outside Homebrew/ruby. From the command
line:

$ ../gcc-7.1.0/configure --build=x86_64-apple-darwin17.0.0
--prefix=/usr/local/Cellar/gcc/7.1.0 --with-gmp=/usr/local/opt/gmp
--with-mpfr=/usr/local/opt/mpfr --with-mpc=/usr/local/opt/libmpc
--with-isl=/usr/local/opt/isl --enable-checking=release
--with-native-system-header-dir=/usr/include
--with-sysroot=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.13.sdk
$ make -j4

The only thing I can think of is that maybe, just maybe, it's due to filesystem
timestamp granularity? My 10.13 system is running on APFS filesystem, which has
1 ns granularity (smaller than 1 s for HFS+).
