[avr-gcc-list] "sized pointer" increment

[Dusan Ferbas]

Hi guys,

"pointer size" increments, in a snippet below, work with 
WinAVR-20060421 (avr-gcc 3.4.6), but does not in WinAVR-20071221 
(avr-gcc 4.2.2).
Compiler claims casted pointer as not an lvalue.
Is this correct behaviour ?

        unsigned char   *p_received_data;

        boot_info_header->section_length = *((unsigned 
long*)p_received_data)++;
        boot_info_header->address = *((unsigned short*)p_received_data)++;
