Geoff,

I would suggest instead doing:

 gcc -o first first.o c:\mingw\lib\libtiff.lib

or even:

  gcc first.c -o first -ltiff

The stuff you are missing is C support library stuff and if you link your program with the compiler it will supply the needed extra libraries.

BTW, this isn't strictly a libtiff question.

Best regards,
