[Bug-gnulib] xgethostname simplification

[Simon Josefsson]

In GSS I use a custom xalloc module, so I noticed that xgethostname
drag in exit and error but doesn't use them.  Depends-on should only
list modules which the module depend on directly, right?

        * xgethostname.c: Don't include error.h (not used).

2004-08-08  Simon Josefsson  <address@hidden>

        * modules/xgethostname (Depends-on): Remove exit and error (not
        used).
