the 0XC000007B incorrect image error dialog I am geting on startup of my 64-bit
program leads me to conclude that:
- since crtdll.dll is a 32-bit dll (ms stored 32-bit dll's and exes in
c:\windows\SysWOW64 and 64-bit stuff in c:\windows\system32 go figure),
- and crtdll.dll is not available in system32 but only in syswow64 on win7,
- and %systemroot%\syswow64 is not in the path when you install windows,
the 64-bit compilers should not use this DLL (mixing 32-bit DLL with 64-bit exe
can't be good???).
the incorrect image error I wonder about. perhaps it'f elf or coff when it
should be something else, or is not in proper exe format for 64-bit? or is it
the mixture of 64-bit exe with dll? or both?
