#109 Duplicated usage of AC_USE_SYSTEM_EXTENSIONS

[Mario Sanchez Prada]

In configure.ac there are two uses of AC_USE_SYSTEM_EXTENSIONS:

[...]
# define things like _GNU_SOURCE appropriately
AC_USE_SYSTEM_EXTENSIONS

# really severe build strictness
AM_INIT_AUTOMAKE([-Wall gnits 1.11.2])
# Change to using into-in-builddir in the future:
#AM_INIT_AUTOMAKE([info-in-builddir -Wall -Werror gnits 1.14])

# From patch 2803433, request system extensions to generate 64-bit safe code
AC_USE_SYSTEM_EXTENSIONS
[...]

Either the first or the second one is redundant so one should be removed but beware, there's a bug introduced in automake 1.14 (fixed in 1.15) that would potentially cause trouble if you put it before AM_INIT_AUTOMAKE.

Thus, I'd probably leave the second one only, to be safer. More info about this automake bug here: http://debbugs.gnu.org/cgi/bugreport.cgi?bug=15981
