求救，postgresql编译问题

我的程序编译通不过，总是报这样的错：
test1.c:9: stray '\241' in program
test1.c:9: redeclaration of `pghost'
test1.c:5: `pghost' previously declared here
test1.c:10: stray '\241' in program
test1.c:10: stray '\241' in program
test1.c:10: stray '\241' in program
test1.c:10: stray '\241' in program
test1.c:10: stray '\241' in program
test1.c:10: stray '\241' in program
test1.c:10: stray '\241' in program
test1.c:10: stray '\241' in program
test1.c:10: stray '\241' in program
test1.c:10: stray '\241' in program
test1.c:10: redeclaration of `pgport'
test1.c:6: `pgport' previously declared here
test1.c:11: stray '\241' in program
test1.c:11: stray '\241' in program
请问大虾们，怎么会是呀？请给我个简单的连接数据库的c程序。　　　　　　

你将系统安装的PGSQL删了吗？将/var/lib/pgsql目录下清空了吗？
