Hi, making the change to config.sub is fine. What I don't get is the explicit definition for struct _IO_FILE in sqVirtualMachine.c. Shouldn't we do something like
#if TheDefimneThatSaysWereUsingMUSL # include <whereever/lives/stdio.h> #endif
The key here is to not break the existing build, and including a possibly incompatible definition of struct _IO_FILE in sqVirtualMachine.c is almost guaranteed to break the build somewhere :-)
