+ But only root function main() contains instructions that
+ set 16-byte alignment for stack pointer. And another functions
+ just keep alignment, if it was set in some parent function.
+
+ The problem:
+ if we create new thread in MinGW (GCC) 32-bit x86 via _beginthreadex() or CreateThread(),
+ the root function of thread doesn't set 16-byte alignment.
+ And stack frames in all child functions also will be unaligned in that case.
+
+ Here we set (force_align_arg_pointer) attribute for root function of new thread.
+ Do we need (force_align_arg_pointer) also for another systems? */
