boost::filesystem compile error on solaris 10

[robin.nicholson@…]

fails to compile because fchmodat is not supported on solaris 10. (Compiler used was gcc 4.7.1)

libs/filesystem/src/operations.cpp: In function 'void boost_1_50_0::filesystem::detail::permissions(const boost_1_50_0::filesystem::path&, boost_1_50_0::filesystem::perms, boost_1_50_0::system::error_code*)': libs/filesystem/src/operations.cpp:1401:11: error: '::fchmodat' has not been declared

uname -a SunOS 5.10 Generic_141444-09 sun4u sparc SUNW,Sun-Fire-V490

This looks like a duplicate of #6659... you may want to add your testcase to that bug (although it has been ignored for 4 months).

The issue has been addresses before but not for compiling with gcc on solaris line 1400 could have

&& !defined(sun)

added to it to fix the problem

[Beman Dawes]

(In [79484]) Fix #6659 and #7051, fchmodat supported only on Solaris 11. Disable fchmodat for both Sun and GCC compilers regardless of OS version; a runtime check is too much trouble.
