I'd say so too. This may lead to unexpected compilation problems on more exotic platforms, but it's worth it IMHO

Hi TSP admin's

what do you think about this?
Is it acceptable for you to enable _GNU_SOURCE
when we use gcc compiler?

I'm tempt to say yes but I'd like to have your opinion.

Hi Robert,

I think _GNU_SOURCE usage should be avoided alltogether
in fact tspfs may currently be the only exception.

TSPFS is using FUSE
which is only available on Linux.
I don't even know if fuse may be compiled/used with
alternate compiler for Linux so I don't mind
_GNU_SOURCE for tspfs.

We specically avoid GNU specifics for "generic" part of TSP.

So your change may be OK
since if we have GNU compiler adding _GNU_SOURCE is not that
bad, but I would like testing for a compilation using
alternative compiler.

May be SunStudio for Linux
or icc

or any other compiler on non Linux platform.

In the gcc header file netdb.h the alias h_addr for h_addr_list[0] has been placed under __USE_MISC ||  __USE_GNU
These flags in turn are being enabled by _BSD_SOURCE or _SVID_SOURCE and the latter by _GNU_SOURCE.
I experimented with _BSD_SOURCE and the compilation failed as some other files required _SVID_SOURCE.
Then I experimented with _GNU_SOURCE and found that a couple of other files enabled the flag as well (tspfs.[ch]). (plus it sets the internal __USE_GNU flag).
As some of the files already rely on the _GNU_SOURCE flag I decided to put it under the CMAKE_COMPILER_IS_GCC in the top-level CMakeLists.txt file.
This requires then the removal of the locally set flags in tspfs.[ch].
