for me it is a mingw program issue. Just personal opinion.

That is expected. "objdump -x" provides all the info, while
"ldd" only the list of dlls available on the PATH

to me it seems than in one case

 >>> $ ldd mung.exe
 >>>           ntdll.dll => /xp0/WINDOWS/system32/ntdll.dll (0x7c900000)
 >>>           kernel32.dll => /xp0/WINDOWS/system32/kernel32.dll 
(0x7c800000)

ldd find only these dll's in the PATH

While in the second case

 >>> while in the copy directory, ldd shows:
 >>> $ ldd mung.exe
 >>>           ntdll.dll => /xp0/WINDOWS/system32/ntdll.dll (0x7c900000)
 >> [cut]
 >>>           glut32.dll => /usr/bin/glut32.dll (0x10000000)

 >>>           libgcc_s_sjlj-1.dll =>
 >>>           /usr/i686-w64-mingw32/sys-root/mingw/bin/libgcc_s_sjlj-1.dll
 >>>           (0x6cec0000)
 >>>           libstdc++-6.dll =>
 >>>           /usr/i686-w64-mingw32/sys-root/mingw/bin/libstdc++-6.dll
 >>>           (0x6fc40000)

ldd find all dll's on the PATH
