aceserver solaris

[Danielle et jean Thierry-Mieg]

this is a solaris bug,
htey have several versions of rpcgen, some of them bugged

i do have a binary aceserver for solaris
i ll add it to ncbi, but i hope it does not depend
on the excat solaris machine

the problem is:
 the rpc self generated code wrpc/rpcace_svc.c
forks AFTERR establishing the pipe

the rest of this message contained a correct file:

wrpc/rpcace_svc.c to be substituted inside
wrpc directory after rpcgen has run:

make aceserver:
  this will call rpcgen and cretae the faulty rpcace_svc.c
cp the fixed rpcace_svc.c:
  cp rpcace_svc.c.ok rpcace_svc.c
touch  rpcace_svc.c
 to garantee that mkake will not overwrite it
make aceserver
 verify that make recompiles the new rpcace_svc.c and relinks
 and that after that rpcace_svc.c is still the fixed one !

If the server still does not work, let me know
here is rpcace_svc.c.ok FOR SOLARIS machines ONLY
