The current version of aitTypes,h has the following exclusions around  line 91 in aitTypes.h.
In your version you may be required to add "&&!defined(sgi)" in order to get the code to 
compile on SGI hosts. Hopefully we will arrive at a more general solution in the future.

#if (_POSIX_C_SOURCE < 3) && !defined(SOLARIS) && !defined(HP_UX) && !defined(linux) &&!defined(sgi)

Following the convention for all EPICS header files, the file ../base/src/gdd/aitTypes.h 
is installed into ../base/include/aitTypes.h during the EPICS base build procedure. Programs 
built outside of EPICS base are compiled specifying only the following two EPICS include file search locations.

<EPICS_BASE/include 
<EPICS_BASE/include/os/<your operating system>
