Compiling error

Good afternoon. Smaug1.4a_mxp.tar downloaded the forum here, I renamed the makefile because I use cygwin. I installed cygwin as the tutorial available here in the forum and ran the commands: make clean and then make. But had this error. How can I fix it?

I thank the attention.
And taking another doubt, this version has the mobprogram the program command?
If you do not like to add to mobrpromgram this command?
