This fixes crash on macos due to wrong hash() being linked in.
It also makes sure that proper function defs are declared and available
(as required by C99) to make compile possible in newer compilers (e.g.
Apple clang) and to some extend prevent similar linkage issues happening
again.
time warnings and errors. Removed the "-lazy" option from the
Tcl load command, which is not needed when the stubs libraries
are compiled in correctly, and which causes issues on some
systems (e.g., Mac OS). Thanks to Matt Guthaus for the patch.
variables to iterate over hash table contents. This led to the
inability to nest hash table iterators. Fixed by defining a
wrapper structure that holds the actual hash table plus the size
and iterator indexes. Not only does this solve the nesting
problem, but it also avoids the need to pass the hash table size
on every call, and that reduces the number of ways a hash table
subroutine can go wrong (e.g., cannot access the table out of
bounds simply by passing a size that is larger than was used to
initialize the table).
