It doesn't seem to work - try setting WARNS=4 and then compiling
usr.bin/getcat. I've just checked and it seems that -W also sets
-Wuninitialised:
14:29:gonzo 29% gcc -O -W -c blah.c
blah.c: In function `f':
blah.c:2: warning: `i' might be used uninitialized in this function
14:29:gonzo 30% gcc -O -W -Wno-uninitialized -c blah.c
14:30:gonzo 31% cat blah.c
void f() { int i; g(i); }
Did the patch look OK, or is there some other way I should be doing
this?
David.
