When I try to compile Exim 4.x on Solaris 2.5.1 I get an error along the lines of no such field in struct as 'value.ui32**.

Look in the Exim file***OS/os.h-SunOS5.h* *for the line

::

#define LOAD_AVG_FIELD value.ui32

and change* ui32 to ul *(that's u followed by the letter ell, not the digit one). Solaris 2.5.1 is getting very old now...
