Updated sgml
FIXED: Use atomic instructions for managing the thread signal mask.
Using a mutex (as it was) can lead to a deadlock if raiseSignal() is
interrupted by a signal.
PORT: Avoid dependency on 8-byte atomic operations on 32-bit platforms.
Allows compiling on ARMv6 (e.g., the Raspberry Pi)
Cleanup unreachable code.  EOF is trapped where the trace reply is read.
FIXED: possible signed overflow when creating stand-alone resource archives. Very unlikely to occur in practice
FIXED: Reading one byte after static array (innocent).
GIT: Avoid directory names in git submodules to facilitate github

Conflicts:
	.gitmodules
Fixed prepare for submodule sync
