* win/configure:
* win/configure.in: Define HAVE_ALLOCA_GCC_INLINE
when we detect that no alloca function is found
in malloc.h and we are compiling with GCC.
Remove HAVE_NO_ALLOC_DECL define.
* win/tclWin32Dll.c (TclpCheckStackSpace):
Don't define alloca as a cdecl function.
Doing this caused a tricky runtime bug because
the _alloca function expects the size argument
to be passed in a register and not on the stack.
To fix this problem, we use inline ASM when
compiling with gcc to invoke _alloca with the
size argument loaded into a register.
