RSB 4.11.2-rc4 rtems-arm build fails on Windows

[Linda Huxley]

Hi Chris,

I dug around in the the ARM build log file, and first I'm seeing this:

make[6]: Entering directory 
'/C/opt/rtems/r4.11.2/rtems/build/ark4r1/arm-rtems4.11-kernel-4.11.2-rc4-1-4.11.2-rc4/build/arm-rtems4.11/c/altcycv_devkit/lib/libbsp/arm/altera-cyclone-v'

then a little later:

arm-rtems4.11-gcc.exe: error: 
../../../../../../../../rtems-4.11.2-rc4/c/src/lib/libbsp/arm/altera-cyclone-v/hwlib/src/hwmgr/alt_16550_uart.c: 
No such file or directory

When I combine the directory with the path to "alt_16550_uart.c" I get a 
string with a length of 264 bytes.  I did some testing, and it seems 
that at some point Windows does just blindly concatenate the two strings 
together.  So the resulting string is about 8 bytes too long.

I'm not sure what the best fix might be, but I'll see if removing 
"/c/opt/rtems" from the build path will help.

Regards,

Linda
