[bug #32383] NSClassFromString returns nil on MinGw if the string class is in a shared library and hasn't yet been used

[Brock Erwin]

Follow-up Comment #4, bug #32383 (project gnustep):

Richard:

I have attached a new tarball with a GNUmakefile which I believe should
compile on your system.

Matt & Nicola:

I agree that this definitely sounds like a problem with the compiler/linker
and not a bug in NSClassFromString.  As you point out and as I noticed as well
on my GNU/Linux/Ubuntu system, it seems as though the compiler/linker loads
all classes from shared libraries by default, but on windows this does not
seem to be the case (for DLLs).

"Anyhow, Brock, 
making sure all symbols in DLLs are loaded is a typical 
Windows problem. Have you tried referencing symbols in the DLL 
in your program to make sure it is loaded up ? Eg, some people 
add a global function pointer variable to their program, and 
initialize it by pointing it to a function in the DLL they are 
loading, to make sure the DLL is loaded when the program starts 
up."

If you look at the file 'test.m' which I attached on line 14:

 13     // UNCOMMENT the following line, and you will see the bug
dissappear...
 14     //foo = [MYClass class];

-- is this what you are referring to in order to get the class loaded?
