  304.   Furthermore, it tests that if a program requires older standard
    305. 

  305.   (_XOPEN_SOURCE<600 or _POSIX_C_SOURCE<200112L) it cannot be
    306. 

  306.   run on a new compiler (that defines _STDC_C99) and issues an #error.
    307. 

  307.   It's also an #error if a program requires new standard (_XOPEN_SOURCE=600
    308. 

  308.   or _POSIX_C_SOURCE=200112L) and a compiler does not define _STDC_C99.
    309. 

    310. 

  310.   To add more to this mess, Sun Studio C compiler defines _STDC_C99 while
    311. 

  311.   C++ compiler does not!
    312. 

    313. 

  313.   So, in a desperate attempt to get correct prototypes for both
    314. 

  314.   C and C++ code, we define either _XOPEN_SOURCE=600 or _XOPEN_SOURCE=500
    315. 

  315.   depending on the compiler's announced C standard support.
    316. 

    317. 

  317.   Cleaner solutions are welcome.
