DJGPP indeed does not support Turbo C-style pseudo-register variables, so 
you will have to replace it by inline assembly.  Some of the differences 
between Intel ASM syntax and AT&T syntax are explained in the DJGPP FAQ 
list (available as faq102.zip from the same place you get DJGPP), Chapter 
17.  To learn about the GCC inline assembly facilities, read the relevant 
chapters of the GCC Info pages.  You can also look into the DJGPP library 
sources for examples of inline assembly.
