[bug #34608] comparison of unsigned expression < 0 is always false

[Paul D. Smith]

Follow-up Comment #6, bug #34608 (project make):

This is what I get:


$ cat foo.c
#define INTEGER_TYPE_SIGNED(t) !((t) -1 >= 0)
int foo() { return INTEGER_TYPE_SIGNED(unsigned int); }

$ gcc --version
gcc (Ubuntu/Linaro 4.4.4-14ubuntu5) 4.4.5

$ gcc -Wextra -g -c -o foo.o foo.c
foo.c: In function 'foo':
foo.c:2: warning: comparison of unsigned expression >= 0 is always true
