If you want your function to take parameters in registers (most Amiga
library functions do), then you'll need to use __asm and register commands
like this:

ULONG __saveds __asm Add(register __d0 int a, register __d1 int b)

Tips:

The register name must be in lowercase.  It must be prefixed by two
underscores.

You also need the type of each argument.

When you compile, you need to use -ml on the command line.

If your library calls routines which are in its function table (most libraries
do), then don't use #pragmas for functions in your library.  Instead, use
prototypes formatted just like the function definitions.  You may continue
to use pragmas for functions in other libraries.

With reference to a message that Peter Cherna sent to me about a month ago,
do not perform any library initialization in the file "libinit.c"

Go into your .fd file and check out the name of the base.  If there is no
underscore on the base name, add one.

##base FlowBase		WRONG
##base _FlowBase	BETTER
