Thanks a lot!!
As you say, I have 2 cygwin1.dll in my PC.
When I deleted one in C:\..\SYSTEM ,then
$ cygcheck `gcc -print-prog-name=cc1`
D:\cygwin/lib\gcc/i686-pc-cygwin/3.4.4/cc1.exe
D:\cygwin\bin\cygwin1.dll
C:\WINDOWS\system32\ADVAPI32.DLL
C:\WINDOWS\system32\ntdll.dll
C:\WINDOWS\system32\KERNEL32.dll
C:\WINDOWS\system32\RPCRT4.dll
C:\WINDOWS\system32\Secur32.dll
D:\cygwin\bin\cygiconv-2.dll
D:\cygwin\bin\cygintl-3.dll
And gcc&g++ run!
$ gcc hello.c
$ ./a
Hello World!
Thanks for DaveK,Brian and everyone.
