- added missing include

killme.c

- added new mat verifying that primitives raise exceptions for invalid

arguments based on primdata.ss signatures. fixed some of those

signatures, which weren't otherwise used except for arity checking.

fixed some issues turned up by the test with who reports errors

and how.

- string comparisons (string=?, string-ci<?, etc.) now get out fast

when handed eq arguments.

5_4.ss

- changed representation of most-negative iptr, I32, and I64 to make

Visual C compiler happy. updated windows make files, which had

fallen out of date. added missing hsrc= files sort.h and thread.h

so they show up in the Windows workarea c directory.
