Hi Bob, Thanks. Actually currently I am trying to use a library
generated by DIAB, on uclinux-ggc. Yes, your suggestion will help - I
just need to put #define I was trying to port the code from DIAB to
uclinux-gcc, but the ASSEMBLY code (there is a lot of assembly) will
require a lot of changes (from DIAB to GCC). Hence right now I am just
trying to use the LIBRARY. Porting may be the next step. Thanks again.

As a suggestion #define _memcpy memcpy and #define _memset memset or
vice versa and use GNU C. I though you were porting away from diab?
