While trying to get latest code to build on F17 and other older systems, I noticed
that this code fails to compile:
struct hostapd_wmm_ac_params wmmp[WMM_AC_NUM] = { 0 };
It looks like WMM_AC_NUM is treated as 0, even though the enum defines it
as 4.
Anyone know if this is some particular compiler bug or an acceptable work-around?
Which compilers and versions produced the error and what was the exact
error?
First, I'm using latest upstream with my changes on top, with this work-in-progress patch
to fix openssl compilation. I'm compiling on fedora-17 32-bit currently, since that is the
oldest thing I compile against.
