compiling cpukit/rtems/src/attr.c raises this warning:
cpukit/rtems/src/attr.c:29: warning: no previous prototype for

GCC is correct, the function 'rtems_interrupt_level_attribute' is not declared,
nor is part of any public header in RTEMS.

A grep through the source tree, seems to indicate it is part of some Ada-API
and is only used inside of the testsuite via API-violating hackery:

# grep -R rtems_interrupt_level_attribute cpukit c testsuites
cpukit/rtems/src/attr.c:rtems_attribute rtems_interrupt_level_attribute(
c/src/ada/rtems.ads:   pragma Import (C, Interrupt_Level,
testsuites/sptests/sp37/sp37.doc:  rtems_interrupt_level_attribute
testsuites/sptests/sp37/init.c:extern rtems_attribute
rtems_interrupt_level_attribute(uint32_t level);
testsuites/sptests/sp37/init.c:  level_attribute =
rtems_interrupt_level_attribute( level );
testsuites/sptests/sp37/init.c:  level_attribute =
rtems_interrupt_level_attribute( level );
testsuites/sptests/ChangeLog:   rtems_interrupt_level_attribute.
testsuites/sptests/ChangeLog:   rtems_interrupt_level_attribute body.

No idea what to do about this.

Should this function only be useful as part of the Ada-API, it should be moved
to libgnat.
Should this function be generally useful (I am having doubts, because it's not
used anywhere), a declaration should be added to some public header.

Similar considerations apply to the variable/symbol "rtems_interrupt_mask" from
the same file.
