            Bug ID: 38685
           Summary: -fbracket-depth=N parameter not recognized
           Product: clang
           Version: 6.0
          Hardware: PC
                OS: Windows NT
            Status: NEW
          Severity: normal
          Priority: P
         Component: -New Bugs
          Assignee: unassignedclangbugs at nondot.org

Using macros to hash strings at compile time, the depth of brackets can be
"enormous" but dealt pretty well yet slowly with gcc or msvc. Not in clang.

LVM 6.0.0 x64 win32 :

1>main_tst.c(256): note: use -fbracket-depth=N to increase maximum nesting
level
...
1>clang-cl.exe : warning : unknown argument ignored in clang-cl:
'-fbracket-depth=512' [-Wunknown-argument]

Dudes, in the same output log, seriously...
