[Bug target/14300] New: -pthread doesn't define _REENTRANT in preprocessor on alpha-linux

[qboosh at pld-linux dot org]

I noticed that on alpha-linux using -pthread gcc option doesn't cause cpp
to have _REENTRANT defined (like it is on most archs, including
{i386,amd64,ppc,sparc}-linux).
I found similar report for ia64-linux in your bugzilla (PR 10865, unresolved
yet).

On alpha-linux specs file contains the following options for cpp:
| *cpp:
| %(cpp_subtarget)
|
| *cpp_subtarget:
| -D__ELF__

while for example i386 contains:
| *cpp:
| %{posix:-D_POSIX_SOURCE} %{pthread:-D_REENTRANT}

also on alpha-osf _REENTRANT is defined (from gcc/config/alpha/osf.h):
| #undef CPP_SUBTARGET_SPEC
| #define CPP_SUBTARGET_SPEC \
| "%{pthread|threads:-D_REENTRANT} %{threads:-D_PTHREAD_USE_D4}"

I suppose this is a bug (though bug may be not good word - better to say
accidental inconsistency between ports? as -pthread is documented only for ppc
(RS/6000), but exists in most of ports...), not intentional omission?
