Johnothan King 0e197eee57 Fix mkservice compile errors and add SHOPT_MKSERVICE (#401) 
The unused mkservice and eloop builtins are currently not built, and if
an attempt to compile them is made the build ends in failure. This
commit backports a few build fixes from ksh93v- 2012-08-24 that allow
mkservice and eloop to build (plus an additional compiler warning fix
not in ksh93v-). I've also added a new SHOPT_MKSERVICE setting (turned
off by default) so that mkservice and eloop can be built if the user
chooses to include them in their build of ksh.
