This is indicative of a lua 5.2 API incompatibility issue. This version of the port only supports lua 5.1.

Current upstream repository ​http://code.matthewwild.co.uk/lua-expat is at version 1.3.0 and purports to support lua 5.2.

Required by libquvi-scripts (#42520).

I've attached an update to 1.2.0, as I cannot find 1.3.0.

1.2.0 continues to have issues, which is unsurprising since there have been no tags or releases of Lua 5.2 compatibility work.

The unknown luaL_reg is defined in lua's lauxlib.h and #included in src/lxplib.c, so I'm not sure why the compiler is bailing.

There was a case discrepancy: luaL_reg versus luaL_Reg. Thanks for geekosaur for finding.

Updated to 1.2.0 in r117743.

Since this now builds against Lua 5.2, I'll mark as closed.
