obtained gcc-4.6.4.tar.bz2 from upstream website;upstream
verified gcc-4.6.4.tar.bz2.sig; imported gcc-4.6.4 source tree from verified upstream tarball. downloading a git-generated archive based on the 'upstream' tag should provide you with a source tree that is binary identical to the one extracted from the above tarball. if you have obtained the source via the command 'git clone', however, do note that line-endings of files in your working directory might differ from line-endings of the respective files in the upstream repository.

+// From: Dan Franklin <dan@diamond.bbn.com>
+// Subject: overloaded function resolved incorrectly
+// Date: Tue, 4 May 93 13:59:18 EDT
+
+#include <stdio.h>
+
+// Given the following overloaded function definitions
+
+int ovf(unsigned long, short, short) { printf ("PASS\n"); return 0; }
+int ovf( int, short, unsigned long) { printf ("FAIL\n"); return 1; }
+
+// and the call
+//
+// ovf(unsigned long, unsigned int, unsigned int)
+//
+// it seems to me (and to cfront) that this should resolve to ovf #1 above,
+// but g++ resolves it to ovf #2. Resolving to ovf #1 requires two conversions
+// (unsigned int => short) while resolving to ovf #2 takes two conversions
+// (unsigned long => int, unsigned int => short) and a promotion
+// (unsigned int => unsigned long).
+
+int main(int, char**)
+{
+ unsigned long pixmap = 0;
+ unsigned int x = 0;
+ unsigned int y = 0;
+
+ return ovf(pixmap, x, y);
+}
