Re: dllmain revisited

Hello!

Having read the postings by Sebastian Setzer and Dan Horák, it seems,
that this DLLMAIN problem is not only win95 problem. I have an NT 4.0
server box running with the latest release of cygwin (v1.1) and gcc
2.95.2 and I get the same kind of message about conflicting delcarations
of dllmain, when trying to compile PG7RC2:

> I got an error message, complaining that the declaration of

Has anybody a clue about the origin of this problem? Trying to remove
the conflicting declaration only makes things worse ...

Thanks,

Think i found the catch:

cygwin_dll.h contains these lines:

#define DECLARE_CYGWIN_DLL(Entry)

CDECL_BEGIN
int WINAPI _cygwin_dll_entry (HANDLE h, DWORD reason, void *ptr);

Meaning, that lines 43 and 44 in utils/dllinit.c:

BOOL APIENTRY DllMain(HHINSTANCE hInst, DWORD reason,
LPVOID reserved /* Not used. */ );

should look like this:

BOOL WINAPI DllMain(HANDLE hInst, DWORD reason,
void *reserved /* Not used. */ );

And lines 76-80

BOOL APIENTRY
DllMain(
HINSTANCE hInst /* Library instance handle. */ ,
DWORD reason /* Reason this function is being called. */
,
LPVOID reserved /* Not used. */ )

should look like this

BOOL WINAPI
DllMain(
HANDLE hInst /* Library instance handle. */ ,
DWORD reason /* Reason this function is being called. */
,
void *reserved /* Not used. */ )

LPVOID *reserved /* Not used. */ )

Please correct me if I am wrong.
