Solaris 9 include file <sys/feature_tests.h> refers to X/Open document
System Interfaces and Headers, Issue 5
saying we should define _XOPEN_SOURCE=500 to get POSIX.1c prototypes,
but apparently other systems (namely FreeBSD) don't agree.
On a newer Solaris 10, the above file recognizes also _XOPEN_SOURCE=600.
Furthermore, it tests that if a program requires older standard
(_XOPEN_SOURCE<600 or _POSIX_C_SOURCE<200112L) it cannot be
run on a new compiler (that defines _STDC_C99) and issues an #error.
It's also an #error if a program requires new standard (_XOPEN_SOURCE=600
or _POSIX_C_SOURCE=200112L) and a compiler does not define _STDC_C99.
To add more to this mess, Sun Studio C compiler defines _STDC_C99 while
C++ compiler does not!
So, in a desperate attempt to get correct prototypes for both
C and C++ code, we define either _XOPEN_SOURCE=600 or _XOPEN_SOURCE=500
depending on the compiler's announced C standard support.
Cleaner solutions are welcome.
