unresolved external symbol __mi_msvc_initu when compiling for ARM64 in Visual Studio 2019

[mojca]

When compiling software with Visual Studio 2019 for ARM64, the linker fails with

mimalloc.lib(init.obj) : error LNK2001: unresolved external symbol __mi_msvc_initu
myprogram.exe : fatal error LNK1120: 1 unresolved externals

By replacing

-#ifdef _M_X64
+#if defined(_M_X64) || defined(_M_ARM64)

in

mimalloc/src/init.c

Lines 572 to 577 in 076f815

	#ifdef _M_X64
	__pragma(comment(linker, "/include:" "_mi_msvc_initu"))
	#pragma section(".CRT$XIU", long, read)
	#else
	__pragma(comment(linker, "/include:" "__mi_msvc_initu"))
	#endif

it seems to work, but please note that I neither understand the code nor possess the hardware capable of running the resulting binary.

+1, any progress?

I ran into the same issue while experimenting with mimalloc for CPython. Your fix looks correct and solves the issue for me.
