  fix several bugs in getservent_r
  Gunnar Ritter reported the following:
    moved tcgetpgrp and tcsetpgrp to unistd.h
    adjusted lstat->lstat64 #define to make it work with function pointers
    move __dietlibc__ #define from features.h to diet
  Thomas Ogrisegg sent x86 memccpy and strncpy routines and introduced
    an dietfeatures.h #define WANT_FULL_POSIX_COMPAT
  Thomas also sent me profiling support (so far only on x86, but
    profiling/PORTING describes what needs to be done for other
    architectures)!
  add contrib/dprof.c, also from Thomas.
  Andreas Krennmair sent a patch to add the BSD regex interface to
    libcompat
  Andre noticed that __dtostr never sets first to false.  Oops!
  Andre has provided a largely untested patch that seems to fix the problem.
  Igor Gilitschenski sent a patch for the "%8.7lx" issue.
  abort did not flush all stdio streams
  fix some nasty regular expression bugs
  write a stupid malloc checker (contrib/debug-realloc.c) to help me
    debug my regular expressions.  Please read contrib/debug-realloc.txt
  our i386 memchr,memcmp were broken for the count=0 case
  fix DNS domain search
  i386 memccpy exchanged esi and edi :-(  I should do more checks before
    accepting external code...
