There's a macro named 'itod'. This macro has 2 params on both HP-UX and AIX and deals with inodes and physical blocks. The use of 'itod' (with only one parm) in nntpcache.c and others looks like a conversion macro - nntpcache.c fails to compile. ? on which system is 'itod' defined ? what's the real usage ? please post it .
