Thanks. This is what I did.

Case 1, some code for DJGPP libc. A sed script that extracted the
relevant #defines into a local header file (thank you, Richard Dawe)
and use the created header file in the .S files. 

Case 2, my own pet project. Surround the structs with #ifdef __GNUC__
and #endif (there's only one 32bit header file with this and it's
automatically generated as a glue file between 16bit djasm code
and 32bit code).

Ok. Thanks!


Right,
