exported variables from dll ...

["Philippe GIACINTI" <giac at dalim dot de>]

Dear Colin,

Thank you for your help, your workaround works fine and I can continue my
porting ...


* Anyway I have some general remarks :

	- I had problems only with exported variables from cygwin.dll ( stdout,
stdin through _impure_ptr, ... ). I my point of view exporting a variable from
a dll ( or from a shared library on Unix ) is really a bad thing which must be
replaced by a call to a function ( or C++ method ) which returns the variable.
So the problem is solved for my code ( may be not for inline methods ... ), and
I will try to modify includes files which define _impure_ptr ...

	- May be, it could be cool to modify the linker the following way :
If the linker doesn't find the symbol "foo", it try to resolve it with
__imp_foo
so dlltool doesn't have to generate dummy functions and it will work for
variables ...
It's just an idea, I don't know how the linker works and what it implies in
term of work.


* and I have always some troubles :

	- I tried to use a dll generated with Cygwin32 directly in Visual C++,
but I had a problem with ( probaly ) the initialization of cygwin.dll.
Because my application is linked by VC++ the crt0 init code is not called, and
the global variable "u" which represent the current process is not initialized.

Question : is it possible to let the cygwin.dll initalize itself ?


	- I have a problem with generated C++ code beetween Cygwin32 and VC++
because decorations are different.

Question: is it possible to have the same C++ decoration as VC++ in g++ ?



Thanks for your help
