Teach Solaris that _XOPEN_SOURCE=600 really menas XPG6
In git-compat-util.h, we do
#define _XOPEN_SOURCE 600
#define _XOPEN_SOURCE_EXTENDED 1
unless we are on BSD or SCO.
On OpenSolaris (200811), /usr/include/sys/feature_tests.h has this nice
table:
Feature Test Macro Specification
------------------------------------------------ -------------
_XOPEN_SOURCE XPG3
_XOPEN_SOURCE && _XOPEN_VERSION = 4 XPG4
_XOPEN_SOURCE && _XOPEN_SOURCE_EXTENDED = 1 XPG4v2
_XOPEN_SOURCE = 500 XPG5
_XOPEN_SOURCE = 600 (or POSIX_C_SOURCE=200112L) XPG6
Later in the same header, compilation with -c99 is made to fail if _XPG6 is
not set, like this:
#if defined(_STDC_C99) && (defined(__XOPEN_OR_POSIX) && !defined(_XPG6))
#error "Compiler or options invalid for pre-UNIX 03 X/Open applications \
and pre-2001 POSIX applications"
#elif ...
The problem is that they check things in an order that is inconvenient for
us. When they see _XOPEN_SOURCE_EXTENDED, they declare that we are XPG4v2,
regardless of the value of _XOPEN_SOURCE.
To work around this problem, do not define _XOPEN_SOURCE_EXTENDED on
Sun's.
