The module link is insufficient.:-(

---- Sorry, japanese message change to xxx ---
link.exe @C:\DOCUME~1\hi-saito\LOCALS~1\Temp\nmk03360.
common.obj : error LNK2001: xxxxxx "_pg_qsort" xxxxxx
pg_dump_sort.obj : error LNK2001: xxxxx "_pg_qsort" xxxxx
.\Release\pg_dump.exe : fatal error LNK1120: xxxxxxx
NMAKE : fatal error U1077: 'link.exe' : xxxxx '0x460'
Stop.
