Hello Friends,

I'm writing a C University project and stumbled upon a compiler behavior which I don't understand.

In this file http://code.google.com/p/openu-bsc-maximveksler/source/browse/trunk/20465/semester/tasks/maman14/alpha/maman14/assembler/phaseOne.c?r=112 I've added a call to function named freeAsmInstruction(). This function is defined in file named lineParser.c, yet I haven't updated the matching lineParser.h header file to include this function declaration.

Why does this code compile? I would expect that gcc would fail to compile phaseOne.c until the correct lineParser.h is updated with the declaration of freeAsmInstruction().

I would appreciate an explanation.

Thank you, Maxim
