yes

$ uname -a
CYGWIN_NT-5.1 ITQMOZCAS2NB007 1.5.25(0.156/4/2) 2008-06-12 19:34 i686 Cygwin

$ cygcheck -c -d |grep fortran
gcc4-fortran                   4.3.2-2
libgfortran3                   4.3.2-2

$cygcheck ./conftest-15.exe
.\conftest-15.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
  C:\cygwin\bin\cyggcc_s-1.dll
  C:\cygwin\bin\cyggfortran-3.dll

$ ./conftest-15.exe > conftest.out ; cat conftest.out 
 SUCCESS

$ uname -a 
CYGWIN_NT-5.1 ITQMOZCAS2NB007 1.7.0(0.206/5/3) 2009-03-11 14:08 i686 Cygwin

cygcheck -c -d |grep fortran
gcc4-fortran                   4.3.2-2
libgfortran3                   4.3.2-2

$ cygcheck ./conftest-17.exe
C:\cygwin2\pub\programs\fortran\conftest-17.exe
  C:\cygwin2\bin\cygwin1.dll
    C:\WINDOWS\system32\ADVAPI32.DLL
      C:\WINDOWS\system32\ntdll.dll
      C:\WINDOWS\system32\KERNEL32.dll
      C:\WINDOWS\system32\RPCRT4.dll
  C:\cygwin2\bin\cyggcc_s-1.dll
  C:\cygwin2\bin\cyggfortran-3.dll

$ ./conftest-17.exe > conftest.out ; cat conftest.out 

So I can reproduce it only on cygwin-1.7.
