How can this link order be changed so that the cygwin dll
is linked in first?

Just for comparison, here is the cygcheck output for
my running "hello world" program:

$ cygcheck /tmp/hello.exe
C:/cygwin/tmp/hello.exe
  C:\cygwin\bin\cygwin1.dll
    C:\WINDOWS\system32\ADVAPI32.DLL
      C:\WINDOWS\system32\ntdll.dll
      C:\WINDOWS\system32\KERNEL32.dll
      C:\WINDOWS\system32\RPCRT4.dll

No.
And I did not use that flag.


Maybe you could try to compile and run that program at your site?
Maybe my environment is somehow broken.
I could send you the sources and my cygwin Makefile via private email.

Cheers,

Hans
