That is incorrect. The wall of text consists of hundreds of warnings, some
of which may be spurious, but I wouldn't bet on all of them being so.

"Only one"?


[steve at ando langs]$ gcc -Wall -m32 -O3 qlang/pcc32.c -opcc -lm 2>&1 | grep
uninitialized | wc -l
28


Here's the first ten:


[steve at ando langs]$ gcc -Wall -m32 -O3 qlang/pcc32.c -opcc -lm 2>&1 | grep
uninitialized | head

Its a bit naughty to claim "one" uninitialized variable when there are
somewhere between 10 and 28.
