	Prectete si manual ke gcc (nebo k jakemukoli jinemu kompilatoru
ci linkeru) - zalezi na poradi knihoven na prikazove radce linkeru.
Pokud napisete cc -lm -lcokoli neco.c, tak se bude linkovat libm.o
proti crt0 (coz neudela zadne reference), pak vysledek (porad crt0)
proti libcokoli (zase zadne reference) a vysledek (porad jeste crt0)
proti neco.o a pochopitelne se nenajdou symboly z libm ani z libcokoli,
odkazovane z neco.o.

	Resenim je pouzit tohle:

gcc -I... -o sqlpokus sqlpokus.c -L... -lmysqlclient -lm
