core.sys.posix.grp missing

[Chick Corea]

Using dmd v2.0.47, the following code:

        import core.sys.posix.pwd;
        import core.sys.posix.grp;

yields the following error message:

        Error: module grp is in file 'core/sys/posix/grp.d' which cannot be read

Checking the src/druntime/import directories, I find that a POSIX pwd module
is present:

        src/druntime/import/core/sys/posix/pwd.d
        src/druntime/import/core/sys/posix/pwd.di

But a POSIX grp module is absent.  Neither is there any code related to POSIX
grp functions in any of the modules.  When I found the pwd.d file, I
forgot to check
for a grp.d file, guessing that if one was present then so was the other.

So - am I missing something ?  Or do I need to write one myself ?
