This renames split_style::DOT, to avoid name clashes when building gdb with an old version of Bison (2.3, the version available on macOS). In particular the error looks like: ./split-name.h:34:3: error: expected identifier DOT, ^ m2-exp.c:163:13: note: expanded from macro 'DOT' Bug: https://sourceware.org/bugzilla/show_bug.cgi?id=30286
