Remove _XOPEN_SOURCE=500 -D__EXTENSIONS__

Browse Source 
The value _XOPEN_SOURCE=600 should be used for C99 as we compile at
least with C++11. By doing so the compilation reaches another error in
a third library. Simply removing the option makes the compilation
working normally.

# From the standards(5) manual page:
# The XNS4 specification is safe for use only in ILP32 (32-bit)
# environments and should not be used for LP64 (64-bit)
# application environments. Use XNS5, which has LP64-clean
# interfaces that are portable across ILP32 and LP64 environments.
# [...]
# For platforms supporting the LP64 (64-bit) programming environment
# where the SC5.0 Compilers have been installed, SUSv2-conforming LP64
# applications using XNS5 library calls should be built with command
# lines of the form:
# c89 $(getconf XBS5_LP64_OFF64_CFLAGS) -D_XOPEN_SOURCE=500 \
# $(getconf XBS5_LP64_OFF64_LDFLAGS) foo.c -o foo \
# $(getconf XBS5_LP64_OFF64_LIBS) -lxnet
# So it appears that _XOPEN_SOURCE=500 should be defined when building
# 64-bit applications (on Solaris 7 and better). But then __EXTENSIONS__
# should be defined as well to recover all the default system interface.
