Build failure with Lua 5.5.0: LUA_ERRGCMM undeclared

[Easton97-Jens]

Description:
I noticed a build failure when compiling ModSecurity with Lua 5.5.0 on macOS.
I'm not entirely sure where the issue originates, but the build fails during compilation.

Error message:

engine/lua.cc:158:18: error: use of undeclared identifier 'LUA_ERRGCMM'
case LUA_ERRGCMM:
^

Observation:
It seems related to LUA_ERRGCMM not being defined.
However, I'm not sure whether this is due to changes in Lua (e.g. version 5.5.0) or an issue in the code.

Expected behavior:
The build should either succeed or clearly indicate if a specific Lua version is unsupported.

Actual behavior:
The build fails during compilation.

Steps to reproduce:

Install Lua 5.5.0
Build ModSecurity with Lua support enabled
Run the build
Compilation fails in engine/lua.cc

Additional context:
I noticed this in CI (macOS job with Lua). Other jobs do not seem to be affected.

Hi @Easton97-Jens,

seems like this is a duplicated issue, see

• error: 'LUA_ERRGCMM' was not declared in this scope case LUA_ERRGCMM #2406
• undefined reference to 'lua_pcallk'... #2403
• There may be a mispell in src/engine/lua.cc #2389

I try to solve the workflow and force using Lua < 5.5.

#3524 will be merged soon and (partially) will solve this issue.

Please note that this is just a workaround, do not close this issue until we don't fix the root cause (namely align the code to Lua 5.5).

@Easton97-Jens please pull down the modifications from upstream's v3/master branch.
