thank you for your response but it did not do the trick
if i do a truly 64-bit compile my addresses also become wider :-)

64-Bit Transition Guide: Compiling 64-Bit Code Using GCC
-Wshorten-64-to-32
It works on my machine:
jeremyp@miranda:~ $cat foo.c
#include <stdint.h>
main()
{
int myint;
int64_t myintbig=412345678;
myint=myintbig;
return 0 ;
}
jeremyp@miranda:~ $gcc foo.c
jeremyp@miranda:~ $gcc -Wshorten-64-to-32 foo.c
foo.c: In function ‘main’:
foo.c:7: warning: implicit conversion shortens 64-bit value into a 32-
bit value
jeremyp@miranda:~ $gcc -v
