src/l3ip.c:500: error: lvalue required as left operand of assignmentKeď si ten súbor otvoríš a pozrieš sa na ten riadok, tak prídeš na to, v čom je problém (teda ak vieš aspoň trochu programovať). :)
iprp = (IP_ROUTE *)iprp = iprp->nextip) a až po aplikovaní záplaty bol správny (záplata sa dá aplikovať aj tak, aby sa vrátil ten pôvodný tvar, a to si urobil aj ty, ale program patch ťa na to upozorní).

to se kompilator gcc meni tak ze je zpetne nekompatibilni ?To není zpětná nekompatibilita. Standart C IIRC totiž nic neříká o tom, jak se to má v takémhle případě chovat. Tudíž se kompilátor může zachovat jak chce. GCC obvykle v takových případech vyhazuje různá varování. Nové verze gcc nasadili trend měnit varování za chyby. Je to pochopitelné, protože takový program se může chovat nepředvídatelně a často jsou za to pak biti vývojáři kompilátoru, kteří jsou v tom nevině.
