  Still not working for me.  Get this when I try to link with the libc.a
generated by that method:

/gnu/binutils/obj5/ld/.libs/ld-new: /usr/lib/libcygwin.a(cygwin_crt0.o): bad
reloc address 0x74 in section `.text'

  Sure enough, the text section is only 0x30, but there's no sign of any reloc
at that address.

$ objdump -hr cygwin_crt0.o

cygwin_crt0.o:     file format pe-i386

  So the message could be misleading, I'll have to debug it to see what's
going on.  Also going AFK for a few hours sleep now.  Back later.
