New submission from Josh Triplett <j...@joshtriplett.org>:
In _sre.c, the VTRACE macro normally gets defined to nothing. It later gets
used as the body of control structures such as "else" without braces, which
causes many compilers to warn (to catch stray semicolons like "else;"). This
makes it difficult to compile Python as part of a project which uses -Werror,
such as GRUB. Please consider defining VTRACE as do {} while(0) instead, as
the standard convention for an empty function-like macro with no return value.
