194  saying we should define _XOPEN_SOURCE=500 to get POSIX.1c prototypes,
195  but apparently other systems (namely FreeBSD) don't agree.
196
197  On a newer Solaris 10, the above file recognizes also _XOPEN_SOURCE=600.
198  Furthermore, it tests that if a program requires older standard
199  (_XOPEN_SOURCE<600 or _POSIX_C_SOURCE<200112L) it cannot be
200  run on a new compiler (that defines _STDC_C99) and issues an #error.
201  It's also an #error if a program requires new standard (_XOPEN_SOURCE=600
202  or _POSIX_C_SOURCE=200112L) and a compiler does not define _STDC_C99.
203
204  To add more to this mess, Sun Studio C compiler defines _STDC_C99 while
205  C++ compiler does not!
206
207  So, in a desperate attempt to get correct prototypes for both
208  C and C++ code, we define either _XOPEN_SOURCE=600 or _XOPEN_SOURCE=500
209  depending on the compiler's announced C standard support.
210
211  Cleaner solutions are welcome.
