** Description changed:
+ [Impact]
+ htons() on non x86 platforms is missing a cast to uint16_t which causes FTBFS
of mosh on armel and armhf.
+
+ [Development Fix]
+ This has been fixed in eglibc in Quantal.
+
+ [Stable Fix]
+ A fix can be backported from the Quantal development version into Precise.
+
+ [Test Case]
+ See https://bugs.launchpad.net/ubuntu/+source/eglibc/+bug/1016349/comments/2
+ On how to reproduce with a C program.
+
+ [Regression Potential]
+ This patch affects some of the generic byteswaping code in eglibc. The fix
for x86 arches was already completed years ago, and this patch fixes is for
other arches.

The definition of htons() on platforms other than i386 and amd64 is
missing a cast to uint16_t, which caused this FTBFS of mosh on armel and
armhf:

(We didn’t see this before because this warning is new in GCC 4.7.)
