Comment (by cypherpunks):

 Some linker fun:
 {{{
 --enable-auto-import
     Do sophisticated linking of _symbol to __imp__symbol for DATA imports
 from DLLs, and create the necessary thunking symbols when building the
 import libraries with those DATA exports. Note: Use of the 'auto-import'
 extension will cause the text section of the image file to be made
 writable. This does not conform to the PE-COFF format specification
 published by Microsoft.
 }}}
