scm (5d9-4.1) unstable; urgency=high

  * Non-maintainer upload.
  * High-urgency upload for sarge-targetted RC bugfix.
  * Revert upstream "CAUTIOUS" define, which causes the scm build to
    fail its test suite on alpha (and, it appears, powerpc as well).
    Closes: #245810.

scm (5d9-4) unstable; urgency=low

  * Apply patch from 144062 to fix hppa build (Closes: #144062)
  * Change scm.1 section from Jan 4 200 to 1. (lintian)

scm (5d9-3) unstable; urgency=low

  * Properly clean up info files.
  * Make and install Xlibscm.info.

scm (5d9-2) unstable; urgency=low

  * Fix path problem in slibcat.  Hack at mklibcat.scm.  (Closes: #241510)

scm (5d9-1) unstable; urgency=low

  * New upstream release
  * Merge NMU sparc changes (Closes: #191171, #191356)
  * SHORT_INT is defined for ia64 upstream (Closes: #141928)
  * Scheme imps now grouped in info file (has been for a while)
  (Closes: #115452)

+/* MS Windows signal handling hack added by Rainer Urian */
+/* 
+   SCM crashes on WindowsNT after hitting control-c.
+
+   This is because signal handling in windows console applications is
+   rather different from unix apps.  If control-c is hit on a console
+   application Windows creates a new thread which executes the
+   control-c signal handler.  Now, if the SCM handler does the longjmp
+   back to the repl loop it does it via the stack of the signal
+   handler thread which results always ever is an access violation.
+
+   The solution to this problem is to let the signal handler thread
+   raise a software interrupt in the main thread.
+
+   This is done with the following  steps:
+
+   1. contol-c is hit
+
+   2. Windows creates the signal handler thread which in turn executes
+   the routine win32_sigint as its signal handler.
+
+   3. The handler suspends the main thread and gets the main threads
+   register context.
+
+   4. The handler simulates an interrupt call on the main thread by
+   pointing Eip to the sigintstub stub function and also simulates a
+   pushad , pushf of the main threads registers
+
+   5. The handler resumes the main thread which when scheduled will
+   execute sigintstub, which in turn calls the proper signal interupt
+   (scamble_signal)
