The game has commandline parameters! "--version" is
the most interesting (IMHO):
CivCTP Linux 1.1 Thu Jun 10 19:51:54 PDT 1999
Built with flags:
-O2 -funroll-loops -fno-exceptions -fno-rtti -g -D_REENTRANT -DPACK=__attribute__ ((packed)) -DCIV3_SPECIES=75 -D_BFR_ -malign-double -D_SDL_STATIC_LIB -DSTATICALLY_LINKED
Built with glibc-2.1
I haven't figured out why the game seems to be threaded
(-D_REENTRANT), but the documentation says that the Auto-Save
feature uses a background fork()'ed process ...
