patch to dlls/msvrt/string.c but not to tests/misc.c

UNIX long double != MS long double even when they all use Intel's 80 bit FP
format.
Their sizeof() may diffe.r

Here's a fix to dlls/msvcrt that decouples use of long double on the host OS
from what MS expects.
winetest.exe passes the msvcrt/misc test, proving that stack usage when passing
parameters is correct.

Alas, I've not figured out how to do the same with the test code in
msvcrt/tests/misc.c: It must not declare *pI10_OUTPUT using long double as that
is wrong on every UNIX system where sizeof(long double) != 12. Yet the test
code still wants to make use of some floating point literals.

I.e., msvcrt/tests/misc.c is bogus and still needs a patch.
