We have simple source file: file.64.cpp
int main()
{
#ifdef SOME64
printf("64\r\n");
#else
printf("32\r\n");
#endif
return 0;
}

So. If we build file with that command
$CC -DSOME64 -I../../common/src -O0 -g3 -Wall -c "systemcontroller.64.cpp"
then SOME64 are undefined in file(../../common/src is valid path).
if we erase include block(-I) or write invalid path like this
$CC -DSOME64 -I../../common/src_1 -O0 -g3 -Wall -c "systemcontroller.64.cpp"
than everithing work fine... i mean SOME64 are defined in file.

$CC can be g++, gcc, cc, c++.
