From 49449c30c4d1514486364d1e0dbea6938914b86f Mon Sep 17 00:00:00 2001 From: "Geyslan G. Bem" Date: Mon, 7 Oct 2013 19:16:59 -0300 Subject: x86: mkpiggy.c: Explicitly close the output file Even though the resource is released when the application is closed or when returned from main function, modify the code to make it obvious, and to keep static analysis tools from complaining.
