No, the conform/ data must reflect what's in the standards, not what's in 
glibc.  Since these symbols are not part of POSIX, they must not be 
included in the conform/ data.  And since these symbols are not reserved 
by POSIX, the header must only declare them at all if __USE_GNU is 
defined.  (I expect that might mean defining enum values unconditionally 
with names __ALTMON_* and then conditionally defining the macros in the 
user namespace.)
