No problem for me.
Please note that cyglcms2-2.dll is a indirect dependency of
convert so you may need to reinstall libgs9 and libMagickCore6_2


$ cygcheck convert
Found: E:\cygwin64\bin\convert.exe
Found: E:\cygwin64\bin\convert.exe
Found: C:\WINDOWS\system32\convert.exe
E:\cygwin64\bin\convert.exe

       E:\cygwin64\bin\cygidn-11.dll
       E:\cygwin64\bin\cyglcms2-2.dll

$ cygcheck -f /usr/bin/cyglcms2-2.dll
liblcms2_2-2.6-1

$ cygcheck -f /usr/bin/cyggs-9.dll
libgs9-9.15-2

  $ cygcheck -f /usr/bin/cygMagickCore-6.Q16-2.dll
libMagickCore6_2-6.9.1.3-3

please also note that there is a system utility called in the same way
C:\WINDOWS\system32\convert.exe

so be sure to have cygwin /usr/bin directory in the PATH
before any system one.
