DLL entry point bypass?

[Nobody/Anonymous]

Hello all,
I have a DLL that compiled and worked fine from MSVC++6. After compiling from Dev-Cpp 4.9.6 with GCC 3.2 (MinGW) the DllMain function seems to get bypassed. Here's an example :
(not the actual code)
//main.cpp

int a = 1;

BOOL APIENTRY DllMain(HINSTANCE h, DWORD dwReason, LPVOID pReserved)
{
a++;
return true;
}

EXPORT int __cdecl MyFunction()
{
return a;
}

Calling MyFunction from a program will return 1. If this was compiled with MSVC++6 it would return 2. The difference is critical.

I've tried combinations of most switches listed under DllTool --help and g++ --help etc.

Any ideas?

Ok everyone, you can relax now.

The problem can be fixed (worked around?) by defining DllMain as

extern "C" BOOL APIENTRY DllMain(HINSTANCE h, DWORD dwReason, LPVOID pReserved)
{
return true;
}

geoff (as above)
