[PATCH] D66487: Fix -Wimplicit-fallthrough warnings in regcomp.c

[Nathan Huckleberry via Phabricator via llvm-commits]

Nathan-Huckleberry added a comment.

Maybe replace __has_cpp_attribute with something like this?

  #ifndef has_cpp_attribute
  #ifdef __cplusplus
  # define has_cpp_attribute(x) __has_cpp_attribute(x)
  #else
  # define has_cpp_attribute(x) 0
  #endif
  #endif
