Thread: pgsql-server: Fix function definition that somehow missed being

Log Message:
-----------
Fix function definition that somehow missed being ANSI-fied, and align
it with previous prototype to suppress complaints from picky compilers,
per report from Scott Bailey.  Also, remove substitute strerror
definition --- not needed, since we link this with libpgport.
