I meant "every dependent compiled object included in the libgcc_s_dw2-1.dll
is statically linked"

Official emacs.exe, 2013-03-13 14:38, 9.031.038 bytes

objdump -x emacs.exe | fgrep "DLL Name:" yields

DLL Name: ADVAPI32.DLL
DLL Name: COMCTL32.DLL
DLL Name: COMDLG32.DLL
DLL Name: GDI32.dll
DLL Name: KERNEL32.dll
DLL Name: MPR.DLL
DLL Name: msvcrt.dll
DLL Name: OLE32.dll
DLL Name: SHELL32.DLL
DLL Name: USER32.dll
DLL Name: USP10.DLL
DLL Name: WINMM.DLL
DLL Name: WINSPOOL.DRV

So I asume there is no dependency on libgcc_s_dw2-1.dll.

I have always run emacs.exe with no libgcc_s_dw2-1.dll around.

Miguel.
