The MinGW system() implementation appears to return the straight
return value instead of the waitpid() like result that more
normal systems return. Because of this just return the system()
result without processing for MinGW compilations.
Older version of the MinGW runtime (pre 3.14) just used the
underlying vsnprintf(). Which has some problems. The 3.14 version
has some nice improvements, but it has a sever bug when processing
"%*.*f", -1, -1, <some_real_value>. Because of this we need to use
the underlying version without the enhancements for now.
vvp/main.cc was including asm/page.h on GNU/Linux
systems, though that file does not often exist and
is not necessary.

This patch adds a new flag to vvp "-n" that can be used to make
$stop and hence <Control-C> act like $finish. This may be desired
when using vvp in a non-interactive environment.
This is a direct back port from development that allows vthread
vectors to be converted to real values. This is the first step
in fixing two more failures in the test suite.
This patch fixes another minor problem introduced by the process
end of simulation events. Specifically if the compilation has
indicated we should not run do not even start the main event loop.
This is copied from the development branch. The issue is that calling
vpi_free_object should not really free a call back handle since it is
the real call back object and doing so will invalidate it. This will
likely end with a core dump.
This patch does not add the functionality needed to fix pr1489570, but
it does give an error message that is a bit more descriptive of the
current limitation (cannot do division or modulus with wide value).
This code may be used for more than just a bit select so the error message
is fairly generic. Though it should help in tracking down the real problem
(invalid Verilog code).
