    System Interfaces and Headers, Issue 5

194
  saying we should define _XOPEN_SOURCE=500 to get POSIX.1c prototypes,
unknown's avatar
unknown committed
195
  but apparently other systems (namely FreeBSD) don't agree.
196 197 198 199 200 201 202 203 204 205 206 207 208 209 210 211

  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.
