Problems getting sa-exim/exim integration working

Hi,

I am trying to get sa-exim/exim4 integrated, using sa-exim-4.1 and exim-
4.40, with the installation method #1 (over-writing local_scan.c) but I am 
getting the following error:

--------
gcc -c -O -I.  -o local_scan.o ../src/local_scan.c
../src/local_scan.c:511: warning: #warning you should not worry about 
the "might be clobbered by longjmp", see source
../src/local_scan.c: In function `local_scan':
../src/local_scan.c:551: `SAFEMESGIDCHARS' undeclared (first use in this 
function)
../src/local_scan.c:551: (Each undeclared identifier is reported only once
../src/local_scan.c:551: for each function it appears in.)
../src/local_scan.c:551: parse error before `static'
../src/local_scan.c:706: `SAspamcSockPath' undeclared (first use in this 
function)
make[1]: *** [local_scan.o] Error 1
make[1]: Leaving directory `/usr/local/exim-4.40/build-SunOS5-5.7-sparc'
make: *** [go] Error 2
---------

Looking at the file, I can't immediately see why the second error at least 
occurs: I have follwed the sa-exim instructions and placed the generated sa-
exim.h file in the src directory.

Any clues as to what might be going wrong?

(I am using this method as opposed to #2, localscan, as I am on a Sun 
platform and got library symbol errors when I went for it that way).

Thanks,
Millis
