    304. 

  304.   but apparently other systems (namely FreeBSD) don't agree.
    305. 

    306. 

  306.   On a newer Solaris 10, the above file recognizes also _XOPEN_SOURCE=600.
    307. 

  307.   Furthermore, it tests that if a program requires older standard
    308. 

  308.   (_XOPEN_SOURCE<600 or _POSIX_C_SOURCE<200112L) it cannot be
    309. 

  309.   run on a new compiler (that defines _STDC_C99) and issues an #error.
    310. 

  310.   It's also an #error if a program requires new standard (_XOPEN_SOURCE=600
    311. 

  311.   or _POSIX_C_SOURCE=200112L) and a compiler does not define _STDC_C99.
    312. 

    313. 

  313.   To add more to this mess, Sun Studio C compiler defines _STDC_C99 while
    314. 

  314.   C++ compiler does not!
    315. 

    316. 

  316.   So, in a desperate attempt to get correct prototypes for both
    317. 

  317.   C and C++ code, we define either _XOPEN_SOURCE=600 or _XOPEN_SOURCE=500
    318. 

  318.   depending on the compiler's announced C standard support.
    319. 

    320. 

  320.   Cleaner solutions are welcome.
