We provide gettimeofday() only #ifdef _MSC_VER, but declare it
unconditionally in our own sys/time.h. This is asking for trouble.
Declare it only #ifdef _MSC_VER, else pull in MinGW's sys/time.h with
#include_next.
Likewise, define macros ftruncate(), S_IRUSR & friends in our own
unistd.h only #ifdef _MSC_VER, else pull in MinGW's unistd.h with
#include_next. The #include <getopt.h> is now useless, drop.
src/lib/commands/info.c relies on sys/time.h including windows.h.
Unclean, and no longer the case with MinGW. Include it directly.
MinGW provides EWOULDBLOCK. Drop our replacement.
MinGW provides inet_ntop() in ws2tcpip.h, but only if feature test
macro _WIN32_WINNT >= 0x600, i.e. Windows Vista or later. It defaults
to 0x0502 (Windows Server 2003). Make configure #define _WIN32_WINNT
0x0601 in config.h. This requests Windows 7. Trying to support Vista
feels unwise. Include ws2tcpip.h, and drop our replacement.

O_NONBLOCK from src/lib/w32/w32misc.h is stricly for use with our

typed_wu() either sends a telegram to a single recipient @to, or an

Command functions are traditionally named like the command shortened
to four characters. When this name collides with a keyword or library
function, we abbreviate more: brea(), rea(). A few are unabbreviated,
e.g. execute(). A few have different names, e.g. explain(), not
list().
Commit 23726b379 (v4.3.0) suppressed a GCC warning about carg()
colliding with its built-in function.
Ron Koenderink reported Microsoft Visual Studio 2019 fails to link:
"_carg already defined in ucrtd.lib(ucrtbased.dll)".
Time to clean this up: rename the functions to c_FOO(), where FOO is

When the lot being bid for changes while the player is at the "How
much" prompt, we report "Commodity #%d has changed!", and continue
with the changed lot.
If continuing is okay, we should keep quiet. We did that until commit
40b11c098 "Fix buy not to wipe out concurrent updates", v4.3.27. Okay
when only the lot's price changed.
However, the lot could have gone away, or even be reused for something
else. Failing the command seems safest for the player, so do that.
It's how we use the check_FOO_ok() elsewhere.

Each point of gold resource is worth 5d. Except for mountains, where
it's just 3.75d. This is because a mountain's process efficiency is
only 75%. Has been that way since Empire 3 made mountains mine gold.
This is actually a needless complication: a sector with 75% process
efficiency produces just like one with 100% process efficiency and 75%
of the resource.
Increase mountain process efficiency to 100%. Deities may want to
compensate by adjusting mountains' gold resources.

The work required for a product is traditionally the amount of raw
materials, plus 1 for resource usage, or 1 if using neither. Make it
independently configurable instead, via new product selector bwork,
backed by new struct pchrstr member p_bwork. Keep the required work
exactly the same in the default configuration.
