Don't pass function inlining tweaks to gcc on x86-64 as this actually hurts performance with gcc 3.4.5 (that is currently in Owl) on current processors. With no special options (only -finline-functions), gcc 3.4.5 inlines only s4(), which turns out to actually be optimal for current processors.

Treat AMD's 64-bit processors the same as AMD Athlon for the purpose of selection of optimal 32-bit Blowfish and non-bitslice DES code.

Workaround what appears to be a gcc 4.1.0 strict aliasing bug where the generated code would load BF_current.P[0] and BF_current.P[17] and cache them on the stack or in registers prior to loops which modify BF_current.P[] via ptr.

Moved the Strip cracker to right before the Keyboard one such that we start with simpler and better-commented external mode definitions.

Changed the defaults for the "Strip" cracker to try lengths 4 to 8 and all possible password types. This gives 983,040 password candidates.

Added a couple of comments on the new "keyboard-based" external mode.

Added a sample but fully-functional "keyboard-based" external mode.

Use sysconf(_SC_CLK_TCK) instead of CLK_TCK when _SC_CLK_TCK is known to be available or CLK_TCK is not.

Implemented extra ticks overflow safety - timer-based rather than just crypts count based. The latter was insufficient with slow hashes where a single hash computation takes multiple ticks.

Tell rec_done() to save (update) the recovery file when we're in batch mode and there's stuff left to crack (by the next pass).

Fixed a bug introduced with 1.6.40 which caused spurious "charset file changed" errors in batch mode if interrupted and restored before pass 3. Thanks to Frank Dittrich for the bug report.

Handle 8-bit characters in external mode program sources correctly. Before this change, they would be misinterpreted as EOF. Thanks to Frank Dittrich for the bug report.

Added a separate DO_ALIGN(5) (cache line alignment) after a possible switch to .bss from .data or .text (the latter is used for some data on DJGPP builds).

1.7.0.1; Added "notes to packagers".

Assume gcc 2.95+ with DOS and Win32 builds. These versions of gcc have introduced extra stack alignment to avoid huge penalties of MMX, SSE, and floating point operations on unaligned variables on the stack. In John, we are not using any floating point and none of the MMX instructions refer to locations on the stack. Thus, this extra alignment is not needed and we now disable it with -mpreferred-stack-boundary=2 to avoid the overhead on function entry associated with this gcc feature.

On Windows, install the Cygwin signal handlers in addition to the use of SetConsoleCtrlHandler(). This actually makes a difference when John is run from within an SSH session (via Cygwin builds of sshd and bash), as well as possibly in other cases.

In rec_done(), do a log_flush() even if the session completes normally (that is, if it is not aborted). This is needed to hopefully update the pot file prior to our removal of the crash recovery file.

Added a fairly generic note on alternate John executables in binary distributions. In practice, this is expected to apply to the official DOS and Win32 distributions. John currently supports runtime "CPU fallbacks" on Unix, but not on DOS and Win32.
