#ifdef to remove Glux functionality completely?

[Kroc]

I'm mainly thinking of retro systems and developing using PunyInform here. On EPOC32, for example, the binary size is ~500KB which for this platform is outrageously large and I'd like to cut that down if at all possible. The Frotz interpreter for the system can't play Glulx files anyway, so this functionality is surplus.

The code is pretty finely divided -- there's lots of functions which have "if (glulx_mode)" clauses. (Over 160 at a quick count.) Making that a compile-time option would be very messy, and the number of people who would benefit is probably, um, you.

You could try making glulx_mode a constant or a define with a value of zero and see if your compiler is smart enough to leave the code out entirely.

[erkyrath]

I'm sure my compiler is that smart, but that doesn't help someone compiling with a C90 toolset on EPOC32!

[Kroc]

EPOC32 code is compiled with VC6 on Win2000 and an ancient custom version of GCC, not on the device itself. Whilst old, they might be smart enough to remove the dead code.

A quick experiment finds that changing glulx_mode from a variable to #define glulx_mode (0) reduces the binary size by about 18%. (clang-1205.0.22.9 on MacOS.)
