 The current `libtapi` @1100.0.11_0 has built after I added the following
 patch:

 Slashes))
          CurPtr += 16;
  #else
        // Scan for '/' quickly.  Many block comments are very large.

 Once Lexer.cpp is patched, it builds normally with macports-gcc-11:
 ```
 36-73% port -v installed libtapi
 The following ports are currently installed:
   libtapi @1000.10.8_1 requested_variants='' platform='darwin 10'
 archs='ppc' date='2022-03-20T07:55:02+0800'
   libtapi @1100.0.11_0 (active) requested_variants='' platform='darwin 10'
 archs='ppc' date='2022-03-21T20:55:45+0800'
 ```
