Hi,

	I'm attempting to compile the latest version of EPICS and I'm
running into problems compiling gdd -- which uses the sgi C++
(IRIX 6.2 ) compiler.
The problem is:

gmake[1]: Entering directory
`/projects/711/online_1/epics/v3_13b11/base/src/gdd/O.sgi'
CC +p +w  -O   -DSGI  -I. -I..  -I../../../include -I../../../include
-I../../../include/os/sgi -DUNIX     -c  ../genApps.cc
"../aitTypes.h", line 83: error(3337): invalid redeclaration of type name
          "timespec" (declared at line 11 of "/usr/include/sys/ptimers.h")
  struct timespec
         ^

1 error detected in the compilation of "../genApps.cc".
gmake[1]: *** [genApps.o] Error 1
gmake[1]: Leaving directory
`/projects/711/online_1/epics/v3_13b11/base/src/gdd/O.sgi'
gmake: *** [install.sgi] Error 2

*********

Which I have determined is due to the fact that _POSIX_C_SOURCE is < 3 for 
the sgi os, and struct timespec  is defined elsewhere: in sys/ptimers.h

aitTypes.h: 

#ifndef vxWorks
#if (_POSIX_C_SOURCE < 3) && !defined(solaris) && !defined(SOLARIS)
struct timespec
{
        time_t tv_sec;
        long tv_nsec;
};
typedef struct timespec timespec;
#endif
#endif

	I have fixed the problem by additing two additional conditionals:
aitTypes.h:

#ifndef vxWorks
#if (_POSIX_C_SOURCE < 3) && !defined(solaris) && !defined(SOLARIS) &&
!defined(sgi) && !defined(SGI)
struct timespec
{
        time_t tv_sec;
        long tv_nsec;
};
typedef struct timespec timespec;
#endif
#endif

	I could not find where _POSIX_C_SOURCE is defined in the configure
files.   Can someone tell me where I can set this variable so that the
fix can avoid changing the code?  

	Thanks, 

		Jeff
