[avr-libc-dev] Can pgmspace.h __LPM_xxx__ macros become inline fn's?

[Bill Somerville]

Is there any reason why the LPM macros in avr/pgmspace.h cannot be
reimplemented as inline functions?

E.g.:

__inline__
uint8_t
__LPM_classic__( uint16_t addr )
{
   uint8_t result;
   __asm__
          (
                 "lpm" "\n\t"
                 "mov %0, r0" "\n\t"
                 : "=r" (result)
                 : "z" (addr)
                 : "r0"
                 );
   return result;
}

This avoids warnings in C with -pedantic compiler switch, makes the code
leagal in C++ (it is an error with -pedantic switch in C++).
