+Add checks to "configure" to see whether _POSIX_PTHREAD_SEMANTICS needs\r
+to be defined to get the right number of arguments in the prototypes for\r
+getpwuid_r(). Solaris' default implementation conforms to POSIX.1c\r
+Draft 6, rather than the final POSIX.1c spec. The standards-compliant\r
+version can be used by defining _POSIX_PTHREAD_SEMANTICS.\r
+\r
+This change also adds the file "compat/check_getpwuid.c", which\r
+configure uses to perform its check, and modifies compat/compat.h to\r
+define _POSIX_PTHREAD_SEMANTICS if configure detected it was needed.\r
