C++ source code
I just tried to compile the package libwvstreams-4.6.1-4
on gcc-4.8 trunk dated 20120415 on an AMD x86_64 box.
The compiler said
linuxstreams/wvinterface.cc: In member function 'int
WvInterface::delroute(const WvIPNet&, const WvIPAddr&, int, WvStringParm)':
linuxstreams/wvinterface.cc:479:5: error: size of loop 2 should be 0, not 1
int WvInterface::delroute(const WvIPNet &dest, const WvIPAddr &gw,
^
linuxstreams/wvinterface.cc:479:5: error: bb 89 do not belong to loop 2
int WvInterface::delroute(const WvIPNet &dest, const WvIPAddr &gw,
