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.
