The public bits.h on x86 and x86_64 unconditionally defined REG_R8 (and friends) as macros. Including <sys/ucontext.h> alongside <libucontext/libucontext.h> then breaks because glibc declares the same names as enum members, which the preprocessor rewrites into invalid syntax. Rename the public macros to LIBUCONTEXT_REG_* so libucontext stops shadowing libc symbols.
