If input objects contains a section not defined in a linker's script, ld 
produces "invalid Windows NT image" because this section is not aligned on 
a page boundary. Try to compile:

int __attribute__((section("mysection"))) i;
main(){}

Look at VMA of "mysection" section:

section.exe:     file format pei-i386

Sections:
Idx Name          Size      VMA       LMA       File off  Algn
  0 .text         00000200  00401000  00000198  00000400  2**2
