"dumpbin mydll.dll" will show section names and sizes

I have 2 builds of PLplot.dll - both are the same size (3,327,028 bytes). I have named one of them PLplot_broken.dll, and the other PLplot_ok.dll. They can be obtained from: 
http://www.sisyphusion.tk/junk/PLplot_broken.dll
and
http://www.sisyphusion.tk/junk/PLplot_ok.dll

[download]
Both were built using the same compiler, and against the same plplot static library.
Running 'dumpbin PLplot_broken.dll' and 'dumpbin PLplot_ok.dll produces identical results (except of course, for the file name that is reported): 
Microsoft (R) COFF/PE Dumper Version 7.00.9466

Any advice on how I might be able to come to an understanding of why one is ok, but the other not, would be most welcome.

Cheers,
Rob
