| |
Hi,
Debian unstable now has glibc 2.3.2 and includes kernel headers from "2.5.999-test7-bk-8".
$ gcc --version gcc (GCC) 3.3.2 (Debian)
When compiling my DVB test programs I get warnings like:
test_stc.c:64: warning: signed and unsigned type in conditional expression
with test_stc.c:64 being:
if (ioctl(dmxfd, DMX_GET_STC, &stc) == -1) {
Patch below fixes it for i386, but there are more platforms which need fixing.
