Right, the code does something if fd == 0, but I'm actually trying to avoid learning the internals. Alas this has already chewed up a lot of time and I haven't made any headway trying to reproduce it so I'm about ready to throw in the towel. The code path looks very simple: read the command line and call a function to open a file. The thing is, the file opens just fine, and I can even read from it, but fstat (or the S_ISX macros) puke. I tried stripping out all non-essentials in the Makefile (e.g. it defines __EXTENSIONS__, _GNU_SOURCE, etc. and does some odd stuff with paths) to no avail. In case anybody wants to give it a try on another machine, the function is tcreadfile in tcutil.h in http://sourceforge.net/projects/tokyocabinet/ - remember you have to add #define strtold(a,b) ((long double)strtod((a),(b))) to tcutil.c so tcatoix will compile. Other than that I think it will compile on 1.7.
