g77 executable with largish array fails

["Billinghurst, David \(CALCRTS\)" <david dot billinghurst at comalco dot riotinto dot com dot au>]

The following test case is distilled from the LAPACK timing test cases.  
These used to work on some previous versions of cygwin/g77, but now fail.

The reduced test case is

      integer n
      parameter( n = 39*1024*1024 )  ! 38*1024*1024 is OK
      real    a(n)
      end

When compiled with current cygwin g77 (3.3.3) using the command
	g77 -o labug.exe -O0 labug.f
then run I get the error

C:\cygwin\usr\local\obj\LAPACK\LAPACK-g77\TIMING\LIN\labug.exe (2324): *** MapViewOfFileEx0x728, in_h 0x728) failed, Win32 error 6

The cases passes for n=38*1024*1024
