[Xen-devel] Xen build error based on gcc version

["Todd Deshane" <deshantm@xxxxxxxxx>]

Specific gcc versions seem to have trouble and error out on:

(xen/tools/symbols.c)

symbols.c:84: error: ignoring return value of 'fgets', declared with
attribute warn_unused_result

It has been reported to xen-users are a few occasions, with different
versions of Xen. [1][2][3] Presumably different gcc versions since two
of them are older posts and on different versions of Xen.

I just ran across it on Ubuntu 8.10 gcc version 4.3.2 compiling xen-unstable.

If I switch the compiler to 3.4 or 4.2 it compiles fine.

It is a gcc problem or a problem with the Xen code?

Cheers,
Todd
