Follow up to PR 47375 GETLOG thread safety:

As Rainer Orth reports, the patch breaks bootstrapping on Solaris
http://gcc.gnu.org/ml/fortran/2011-01/msg00245.html

Solaris has two versions of getpwuid_r - one matching a draft and one the final
POSIX version:

#if (_POSIX_C_SOURCE - 0 >= 199506L) || defined(_POSIX_PTHREAD_SEMANTICS)
extern int getpwuid_r(uid_t, struct passwd *, char *, int, struct passwd **);
#else
extern struct passwd *getpwuid_r(uid_t, struct passwd *, char *, int);
#endif
