I'm sorry, but perhaps I wasn't clear in my original email. It wasn't
that IRIX doesn't have fstat, it's that the compiler complained about
the usage:

---begin log--- 
cc-1164 cc: ERROR File = ./serverLog.c, Line = 244
  Argument of type "const char *" is incompatible with parameter of type "int".

      if ((fstat(fileName, &statbuf) == 0)  && (S_ISFIFO(statbuf.st_mode))) {

cc-1164 cc: ERROR File = ./serverLog.c, Line = 317
  Argument of type "const char *" is incompatible with parameter of type "int".

      if ((fstat(fileName, &statbuf) == 0)  && (S_ISFIFO(statbuf.st_mode))) {

2 errors detected in the compilation of "./serverLog.c".
---end log---

According to the IRIX man page for fstat, the first argument of fstat
needs to be an 'int', whereas stat's first argument is a 'char *', which
is how it's being used in this procedure.

Okay, that's fine. Most of the patches are casts (the MIPSpro compilers
seem to be notorious about making sure casts are being used and complain
if they are not). However, one of the patches is something like this
one, which fixes a finger check in afs_vnop_rename.c:

Just thought I'd help...
