Hi Joel,

OK, I will give my opinion about it.

<unistd.h> is a standard feature of POSIX and Solaris.
__EXTENSIONS__ is a standard feature of Solaris, see [1].
<getopt.h> is not a standard feature of Solaris, but has been installed through
CSW packages (not from Sun).
The three, taken together, clash. Whom to blame? The answer is clear IMO:
The non-standard one, /opt/csw/include/getopt.h, ought to be fixed. Or Dagobert
should not use -I/opt/csw/include. Which of these, that's something Dagobert and
the CSW people have to negotiate among themselves.
> Should gnulib be extended to handle this case?
gnulib attempts to give people one way to compile packages on each platform.
If using "cc" does not work on OSF/1, but "cc -nodtk" works, there is no need
for gnulib to support "cc".
If using "gcc -Wall -Werror" does not work on some platform, but "gcc -Wall"
does, there is no need for gnulib to support "gcc -Wall -Werror".
If using "cc -D__EXTENSIONS__ -I/opt/csw/include" does not work on Solaris,
but "cc -D__EXTENSIONS__" works, there is no need for gnulib to support
"cc -D__EXTENSIONS__ -I/opt/csw/include".
