For "tcc -run file.c", I was trying to initialize the FP control
in a function in libtcc1.a (_runmain) before calling main.
Unfortunately that turned out to cause problems with for example
libtcc_test since such usage doesn't necessarily define a 'main'
function.
So for tcc -run we're back to relying on the FP control word
that is set in the startup code of tcc.exe rsp. libtcc.dll.
This fixes part of commit 73faaea227a53e365dd75f1dba7a5071c7b5e541

- Use runtime function for conversion
- Also initialize fp with tcc -run on windows
This fixes a bug where
double x = 1.0;
double y = 1.0000000000000001;
double z = x < y ? 0 : sqrt (x*x - y*y);
caused a bad sqrt because rounding precision for the x < y comparison
was different to the one used within the sqrt function.
This also fixes a bug where
printf("%d, %d", (int)pow(10, 2), (int)pow(10, 2));
would print
100, 99

winapi: add missing WINAPI decl. for some functions

This works only when tcc.exe is compiled using MSC. MinGW does
something in the startup code that defeats it.

To make this the default, enable this line in libtcc.c:tcc_new:
#if defined(TCC_TARGET_PE) && 0
s->leading_underscore = 1;
and then recompile tcc and also libtcc1.a
|

|

This is to make cross build of libtcc1.a easier.

Needed to handle signal() etc. with msvcrt

This enables native unwind semantics with longjmp on
win64 by putting an entry into the .pdata section for
each compiled fuction.
Also, the function now use a fixed stack and store arguments
into X(%rsp) rather than using push.
