bool is dangerous in a time-safe context, because C compilers might
insert a control flow divergence to implement the implicit
normalisation of nonzero integers to 1 when you assign to a bool.
Everywhere else time-safe, I avoid using it; but smemeq has been an
exception until now, because the response to smemeq returning failure
was to do an obvious protocol-level divergence _anyway_ (like
disconnecting due to MAC mismatch).
But I'm about to want to use smemeq in a context where I use the
result _subtly_ and don't want to give away what it is, so now it's
time to get rid of that bool and have smemeq return unsigned.
This is the README for PuTTY, a free Windows and Unix Telnet and SSH
client.
PuTTY is built using CMake <https://cmake.org/>. To compile in the
simplest way (on any of Linux, Windows or Mac), run these commands in
the source directory:
cmake .
cmake --build .
Documentation (in various formats including Windows Help and Unix
`man' pages) is built from the Halibut (`.but') files in the `doc'
subdirectory using `doc/Makefile'. If you aren't using one of our
source snapshots, you'll need to do this yourself. Halibut can be
found at <https://www.chiark.greenend.org.uk/~sgtatham/halibut/>.
The PuTTY home web site is

If you want to send bug reports or feature requests, please read the
Feedback section of the web site before doing so. Sending one-line
reports saying `it doesn't work' will waste your time as much as
ours.
