> 5) rtems-rc-19990202-1.diff/reorg-install.sh
>
> reorg-install.sh fixes a Makefile variable name clash of RTEMS
> configuration files and automake/autoconf standards.
> Until now, RTEMS used $(INSTALL) for install-if-change. Automake and

This problem should and likely was occurring with other BSPs. This is from
Chris' email:
I had a look in the psim bsp for the older snapshot I have and it looks
like you are using the `libbsp/shared/main.c' and this is known to work.
I have just built the powerpc tools, and compiled the bsp. I have not
added the linker command file patch so got the list of linker warnings.
It looks to me like a compiler bug. The `main' call is being inlined and
when that happens the special code to call `__eabi' is not being added
to the inlined version. I have attached a patch which places `main'
after `boot_card' and a call to main is now generated. I have not tested
it but it should work. I also include a dump of `boot_card' and `main'
showing the bug.

code in each BSP's bspstart.c. These changes were:
+ confdefs.h now knows libio's semaphore requirements
+ shared/main.c now copies Configuration to BSP_Configuration
+ shared/main.c fills in the Cpu_table with default values
This removed the need for rtems_libio_config() and the constant
BSP_LIBIO_MAX_FDS in every BSP. Plus now the maximum number of open
files can now be set on the gcc command line.

based on the GNU tools. This usually involved correcting the
type of bsp_start(), bsp_cleanup(), adjusting the start code to
call the right start routine (the shared boot_card()), and then
removing code from bsp_start() which was performed in the new
boot_card()/main() path.
