but, we are compiling C so the names shouldn't be decorated.
undecorating yields the same name:
c:\hannes\>undname DllMain@12
Microsoft (R) C++ Name Undecorator
Copyright (C) Microsoft Corporation. All rights reserved.
Undecoration of :- "DllMain@12"
is :- "DllMain@12"
compiling a little test program:
cat >dllmain.c <<EOF
#include <windows.h>
BOOL WINAPI
DllMain(HANDLE module, DWORD reason, LPVOID reserved)
{ return TRUE;
}
EOF
yields the same exported symbol
C:\Hannes>cl /c dllmain.c

When creating a new dll with VC 6.0, same here
C:\Hannes\testdll\Debug>dumpbin /symbols testdll.obj | grep Main
01B 00000000 SECT6 notype () External | _DllMain@12
as with libecpg
C:\Hannes\pgsql\Debug\libecpg>dumpbin /symbols misc.obj | grep Main
05E 000007B0 SECT5 notype () External | _DllMain@12
Am I missing something?
