the actual warn flags are still there.

leaving Werror in production is ill advised.

i can (and will) still fix build errors as
i see them.

as a result of this, i now also see more info
when i type:

make strict

(this uses clang with -Weverything)

add options for building with urandom+openat and
arc4+openat. useful for emulating a bsd / old linux
environment in modern linux distros, for portability
testing.

these options are not recommended for everyday use.
just use make without any special options, and the
code has build-time OS detection for features like
randomisation/openat2.

-DUSE_ARC4=1

use that

these can be set explicitly in the compiler flags,
e.g.

make CC="cc -DUSE_OPENAT=1 -DUSE_URANDOM=1"

these options, if set to 1, will cause you to use
the code as if it were running on non-linux systems
such as openbsd. of course, some differences will
still exist, but this is useful for portability
testing when compiling on linux.

otherwise, i will end up with a mess like the
one i recently fixed.

we always want to use correct C. the current
spec is set to c99, with -pedantic turned on.

flags now:

-Os -Wall -Wextra -std=c99 -pedantic -Werror

if you do: make hell, you get (uses clang):
-Os -Wall -Wextra -std=c99 -pedantic -Werror -Weverything

i initially loosened up the Makefile rules, so
that the code would be more "portable", but
every compiler worth caring about has these
flags, and turning them on is advisable,
especially pedantic and -std, because you want
to have some guarantee that the compiler is
generating correct code; if the standard is
left ambiguous, you could be introducing subtle
bugs when people compile it, because who knows
what spec the compiler is using?
