From 1630726e849b8b0f1802ad0681b94a64d4851a30 Mon Sep 17 00:00:00 2001 From: Brandon Casey Date: Thu, 27 Aug 2009 11:16:33 -0500 Subject: [PATCH] abspath.c: move declaration of 'len' into inner block and use appropriate type The 'len' variable was declared at the beginning of the make_absolute_path function and also in an inner 'if' block which masked the outer declaration. It is only used in two 'if' blocks, so remove the outer declaration and make a new declaration inside the other 'if' block that uses 'len'.
