#import problems - not able to get working - have you used?

 
Hello MQL'ers...

Can you lend a hand here...yes?

Below I have set out the current environment as relates to the library file and the calling file.

The LIBRARY file:

-- I extracted some global functions and put into separate .mq4 file.
-- I placed this compiled lib file in "...\libraries\" where stdlib is.
-- Compiler warned about no start(). I put in dummy/empty one.
-- Compiler warned that since functions not referenced they would be removed from .ext o/p file. I put dummy calls to functions in start() to satisfy reference requirement.
-- Clean compile -> .ex4 achieved.


The CALLING / REFERENCING .mq4 file:

-- At top of calling .mq4 source is:
#import "loggerLIB_0-1-0.ex4"
bool errorFound ( string msgHdr="" );
void errorMessage( string msgHdr, int err=EMPTY );
int getBarNum ( datetime barDT );
#import

-- Within .mq4 are the same/untouched original function calls (which worked correctly when (the now external/placed into lib file) functions were part of the source file).


QUESTIONS:

1. Where does compiler look when sees #import "..." ?
2. Can formal parameter list contain syntax "(...,int i=0)" ?
3. Further to 2., should that exact formal parameter list be in callers #import block or just "(...,int i)" ?
4. Basically - is syntax "(...,int i=0)" allowed in this library envionment - or only valid in same source syntax usage ?
5. Presently compiler complains about every actual call to functions described in #import block. Why?
6. None of the compiler errors map to the #import block source line numbers. But obviously are related...?

Any information I've missed etc. please say

Thank you very much in advance
