Follow-up Comment #4:

It seems this was compatibility problem with components built with two
different compilers. Once I recompiled also crosser with newer compiler,
freeciv built with newer compiler seems to work.

> freelog("%d - %d (%d) = %d", a, b, time(NULL), b - a) 

Uh, I meant "%lu" instead of "%d".

Follow-up Comment #2, bug #20070 (project freeciv):

Seems to depend on version of MinGW compiler. Downgrading made the problem go
away.
>From how far I got this debugged, seems quite much like compiler bug.

When added in the middle of the code segment giving funny results

b = time(NULL);
freelog("%d - %d (%d)  = %d", a, b, time(NULL), b - a)

gave inconsistent output, i.e., "b - a" was not what one would expect from "a"
and "b", and "b" and directly calling "time(NULL)" gave totally different
values.

Follow-up Comment #1, bug #20070 (project freeciv):

I tried to reproduce this in Linux by commenting out HAVE_GETTIMEOFDAY in
fc_config.h, and thus using same HAVE_FTIME code crosser build seems to be
using (from its fc_config.h) This worked in Linux. Further, making a crosser
build with also HAVE_FTIME commented out -> fallback even further to time()
does not fix the problem in Windows.

Details:

User reported that server always cuts connection to remote client due to ping
timeout. So far we have debugged it down to fact that read_timer_seconds()
returns ping timer value (time between timer start and current time) to be
2^30*1000 seconds.

Also, selection circle animation does not work, which is presumably because
frame change timer does not work.

read_timer_seconds() uses stop_timer() to get the time, and it has several
different conditionally compiled implementations depending on what functions
are available on the platform - it makes sense that platform specific bug is
in there.
