Inconsistent or odd "call cpu_time(x)" behaviour on the current release of
gfortran. I am using the 32 bit Mingw version of gfortran.
C:\>gfortran -v
Using built-in specs.

Configured with: ../trunk/configure --prefix=/mingw

Thread model: win32
gcc version 4.3.0 20080127 (experimental) [trunk revision 131883] (GCC)
The "call cpu_time(x)" operations worked perfectly under a fairly recent
previous release of gfortran (sorry, I no longer have the version info).
I have declared x as follows:-
integer,parameter :: pr=selected_real_kind(6,37)
real(kind=pr) :: x
Unfortunately my code is very lengthy - but I could send it as an example if
really necessary.
