| For the record, this is a "diff" of the Lua DLL supplied with MUSHclient, compared to the standard distribution from www.lua.org:
diff lua-5.1.1/src/Makefile lua-5.1.1.nick/src/Makefile

< CFLAGS= -O2 -Wall $(MYCFLAGS)

> CFLAGS= -O3 -Wall $(MYCFLAGS)

---
> $(MAKE) "LUA_A=lua5.1.dll" "LUA_T=lua.exe" \

Basically the changes are:
- Cranked optimization up from O2 (Optimize even more) to O3 (Optimize yet more).
- Changed the DLL name to lua5.1.dll (rather than lua51.dll).
- Turn off some compatability options: LUA_COMPAT_VARARG, LUA_COMPAT_MOD, LUA_COMPAT_LSTR, LUA_COMPAT_GFIND and LUA_COMPAT_OPENLIB. The comments in the file luaconf.h suggest turning those off as soon as possible, so I have done that.
- Turn on the option LUA_USELONGLONG, and use the appropriate format specifiers, in order to better support conversion from floating point to integers.
It is also worth pointing out that to make the DLL (under Cygwin) I had to use this command line:
make "CC=gcc -mno-cygwin" mingw
If you don't specify "-mno-cygwin" then it builds a dependency on cygwin.dll, which adds an extra DLL to ship, and extra space.

| | If you choose to compile it under MS Visual Studio 6, you have to change the "long long" type to __int64, which is why that is there, commented out. |
