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,
     ^
linuxstreams/wvinterface.cc:479:5: error: loop 2's header does not belong
directly to it
 int WvInterface::delroute(const WvIPNet &dest, const WvIPAddr &gw,
