This is a small fix I made to swank-clisp.lisp.
92c92 < (funcall (find-symbol "gETcURRENTpROCESSiD" :win32))) ---
(funcall (find-symbol "GetCurrentProcessId" :win32)))
Don't ask me why the case of symbols in the Win32 package is reversed...
I mainly work with the Cygwin version of Clisp, but the native Win32 is 30% faster on one of my project.
