with respect to the gcc preprocessor, is it correct to say that, unless i use some of the preprocessor include options to change how include directives are processed, the only difference between the following two statements: #include <fred.h> #include "fred.h" is that the latter will first search the current directory? with that exception, will both forms then search identically based on system directories and "-I" options? i can also see how i can change this with options like "-I-", and -nostdinc and -include, but i wanted to verify what happens with none of these other options. thanks. rday
