I've seen this too.  It also occurs under "gcc -pedantic":

  ltm.h:49: error: array size missing in `luaT_typenames_'

Note that the other LUAI_DDEF's arrays (luaP_opmodes, luaP_opnames,
and luai_ctype_) declare their sizes explicitly.  You could do
likewise for luaT_typenames_.  However, this will still cause a
problem if you attempt to compile the amalgamation as C++ rather than
C.  The following is ok in C (tentative definition) but is an error
(redefinition, lacking extern) in C++:

  static char s[10];
  static char s[10];
