[Confuse-devel] [PATCH 0/5] trivial compile warning fixes

[Carlo Marcelo Arenas Belon]

The following series fixes a series of trivial (and harmless) compilation 
warnings in trunk

  PATCH 1/5: confuse: ensure _GNU_SOURCE is defined before any included header
  PATCH 2/5: confuse: remove unneeded static input() function from generated 
code
  PATCH 3/5: examples: include definition for free() to avoid intrinsic
  PATCH 4/5: examples: match format to data type width in simple.c
  PATCH 5/5: confuse: match sign for parsed octal and hexadecimal input

It has been tested in linux amd64 and x86 with gcc 4.3 (fedora) and gcc 4.1 
(gentoo)
but it should be safe everywhere else.
