Porting C code from Sun Solaris to IBM AIX

I'm having problems porting C code written in Sun Solaris to IBM AIX. It seems that the 2 header files <time.h> and <sys/time.h> in the AIX version is not linked (compared to Solaris) and bound by the following code

#ifdef  _BSD_INCLUDES
#include <time.h>
#endif  /* _BSD_INCLUDES */

Is there any setting that needs to be configured in the C environment? Which standard does IBM AIX comform to (BSD or System V)?

The following errors were generated during compilation when the tm structure in <time.h> is placed together with timeval & timezone structures <sys/time.h> inside the same source file.

"fepfunc1.c", line 59.11: 1506-117 (S) Operand must be a scalar type.
"fepfunc1.c", line 62.17: 1506-022 (S) "tm_year" is not a member of "struct tm".
"fepfunc1.c", line 63.17: 1506-022 (S) "tm_mon" is not a member of "struct tm".
"fepfunc1.c", line 64.17: 1506-022 (S) "tm_mday" is not a member of "struct tm".
"fepfunc1.c", line 94.11: 1506-117 (S) Operand must be a scalar type.

"fepfunc1.c", line 98.25: 1506-022 (S) "tm_min" is not a member of "struct tm".
"fepfunc1.c", line 135.16: 1506-098 (E) Missing argument(s).
"fepfunc1.c", line 136.11: 1506-117 (S) Operand must be a scalar type.

Sun swapped the functionality of time.h and sys/time.h.
I normally just include time.h and define a preprocessor
constant _ALL_SOURCE (as in -D_ALL_SOURCE)
and everything works fine then ...

BTW AIX is more SysV-ish; if you want BSD functionality,
define _BSD. (the appropriate manual pages tell you when
to define this thingy ...)

kind regards,

Jos
