Hi all,

when I try to initalize a long variable with the most negative value of

-2147483648 which should be 0xFFFFFFFF, then I get a compiler warning.

The compiler is gcc version 3.4.5 running on solaris.

long test_var = -2147483648L;
....
../devPbdp.c:80: warning: decimal constant is so large that it is unsigned

-2147483647 is accepted. This problem exists only with long. char and

short can be initialized to the most negative values without any problem.

Any idea? Thank you....
