[Qemu-devel] [PATCH] exec-all: Fix void pointer arithmetic

[Stefan Weil]

Adding an offset to a void pointer works with gcc but is not allowed
by the current C standards. With -pedantic, gcc complains:

exec-all.h:344: error: pointer of type ‘void *’ used in arithmetic

Fix this, and also replace (unsigned int) by (uintptr_t) in the same
statement.
