unknown 8f8ccc4bd5 Replace 'sete_id(__)' calls by 'setre_id(-1,__)' to solve the 
missing prototyped problem (bug#5521).


sql/mysqld.cc:
  Some systems (Unixware, SCO) have no prototypes for 'seteuid()' and
  'setegid()', but have them for 'setreuid()' / 'setregid()'.
  So 'sete_id(__)' calls are replaced by 'setre_id(-1,__)' (bug#5521).

Initialize all MySQL global variables to default values
SYNOPSIS
mysql_init_variables()
NOTES
The reason to set a lot of global variables to zero is to allow one to
restart the embedded server with a clean environment
It's also needed on some exotic platforms where global variables are
not set to 0 when a program starts.
We don't need to set numeric variables refered to in my_long_options
as these are initialized by my_getopt.
