No. FPC is at this time unlikely to perform any optimisations on  
pointer or global variables accesses that would be inhibited by making  
them "volatile" though.

Just declare them as regular functions (with or without inline). It's  
C's way of doing cross-module inlining:
a) the code has to be available in the header file, so the C compiler  
has the C code available to inline when the function is called
b) if you declare the same function more than once, you are going to  
get multiple symbols with the same name and these will clash at link  
time. Therefore such inline functions in headers (which are almost  
always included in more than one source file) have to be declared  
static, as this makes these symbols private to that particular file.
