errors converting PE executable to ELF using objcopy

[David Hovemeyer]

Apologies if this is the wrong list and/or this is a stupid question.

I'm using binutils under cygwin to convert executables in Windows PECOFF
format to ELF.  A while ago, this used to work.  In a more recent version of
cygwin, I am getting some cryptic error messages.  E.g.:

  objcopy -O elf32-i386 user/shell.exe user/shell.exe
  BFD: user/st2UTJnj: warning: allocated section `.text' not in segment
  BFD: user/st2UTJnj: warning: allocated section `.data' not in segment
  BFD: user/st2UTJnj: warning: allocated section `.rdata' not in segment
  BFD: user/st2UTJnj: warning: allocated section `.idata' not in segment

The original user/shell.exe is a statically linked PECOFF executable file.
The resulting user/shell.exe is indeed an ELF file.  However, its
program header contains no segments (which I guess is what the
warning messages are trying to warn me about).

Any ideas how to work around this problem would be greatly
appreciated.
