Simplified the presentation of build date information and added a
command-line utility to retrieve it. - fw/include/atspi/ep0.h, fw/atspi/ep0.c (my_setup): merged ATSPI_BUILD_NUMBER and ATSPI_BUILD_DATE into single ATSPI_BUILD - fw/atspi/ep0.c (my_setup): added work-arounds for compiler bugs - tools/atspi-id/Makefile, tools/atspi-id/atspi-id.c: command-line utility to query hardware and firmware version

/*
|

* SDCC 2.8.0 had a number of code generation bugs that appeared in the big
|
||||
* switch statement of my_setup. SDCC_FORCE_UPDATE forced the value of the
|
||||
* "size" variable to be written to memory. This work-around doesn't seem
|
||||
* to be necessary with 2.9.0, but we keep it around, just in case.
|
||||
*
|
||||
* Unfortunately, the setup->bRequest garbling bug is still with us. Without
|
||||
* the evaluation forced with SDCC_FORCE_EVAL, sdcc gets confused about the
|
||||
* value of setup->bRequest and then rejects all SETUP requests.
