I have got a similar problem in compiling the FLTK framework (LGPL, written in c++, 
http://www.fltk.org) as a dll using mingw32.
I get an error from dlltool :
Syntax error in def file C:\WINDOWS\TEMP\cc560771.def:148
I have managed to intercept this intermediate def file and it also contains non printable characters.

I am using mingw32 gcc version 2.95 19990728 (release) and dllwrap version
GNU C:\MINGW32\BIN\DLLWRAP.EXE 0.2.4

Now if I understood it well dllwrap and dlltool are help programs wrapping ld calls in the making
of dlls and their associated import libs ?

So is this a problem of dllwrap/dlltool or is it a problem in gcc/mingw32 ?

Thank you in advance,
