Hello,
because I am not allowed to use Linux but forced to use Windows 2000 instead I am currently trying to port U-Boot to a Renesas SH7720 (SH-3 core) based platform using Cygwin and a precompiled, freely downloadable gcc 3.4 from KPIT Cummins (http://www.kpitgnutools.com/). Although this is definitely an issue of KPIT and not of U-Boot I am posting here with the hope that someone may have an idea how to fix or work around this problem. I sent the following text to KPIT's support team:

Dear KPIT support team,
I use GNUSHv0501 installed to C:\KPIT_Cummins\GNUSHv0501-ELF from Cygwin. I decided to not install it to its default directory to avoid known Unix trouble when there are white spaces in paths or file names.
While trying to port U-Boot to SH-3 I noticed that /cygdrive/c based paths or mounted paths do not work with the GNUSH tools. c:/ like paths work. This is not problem for GCC tools that come with Cygwin. To reproduce the problem please do the following.
1.) Extract the attached test.tar.bz2 to C:\Playground\test.
2.) Open a Cygwin Bash command line.
3.) Make sure the GNUSH tools are in the path. $ which sh-elf-gcc /cygdrive/c/KPIT_Cummins/GNUSHv0403-ELF/sh-elf/bin/sh-elf-gcc
4.) mkdir /test && mount c:/Playground/test /test && cd /test/src
5.) Compile the program using Cygwin's gcc. $ gcc -I/test/inc -o hello hello.c $ ./hello Hello, world!
6.) Compile the program using GNUSH's gcc. $ sh-elf-gcc -I/test/inc -o hello hello.c hello.c:2:19: hello.h: No such file or directory Fails!
7.) Try a /cygdrive/ path instead. $ sh-elf-gcc -I/cygdrive/c/Playground/test/inc -o hello hello.c hello.c:2:19: hello.h: No such file or directory Fails!
8.) Ty a c:/ path instead. $ sh-elf-gcc -Ic:/Playground/test/inc -o hello hello.c $ sh-elf-objdump -a hello
hello: file format elf32-sh hello Succeeds.
This behavior is very problematic because most Cygwin tools do not return c:/ paths but mounted or /cygdrive/ paths. IMHO there is something severly wrong with GNUSH. How do I get this working with all kinds of legal paths?
To make things worse continue on and try the following:
9.) Compile the program using a different include directory where one header file includes another one. $ gcc -Ic:/Playground/test/inc2 -o hello hello.c Succeeds with Cygwin's gcc.
10.) Now try GNUSH's gcc. $ sh-elf-gcc -Ic:/Playground/test/inc2 -o hello hello.c Succeeds as well (as anticipated).
11.) Convert inc2/universe from directory to symbolic link. $ mv ../inc2/universe ../inc2/parallel && ln -s ../inc2/parallel ../inc2/universe $ ls -la ../inc2 total 2 drwxr-xr-x+ 3 jom2ot mkgroup-l-d 0 May 31 14:43 . drwxrwxrwx+ 5 Administrators ???????? 0 May 31 14:22 .. -rw-r--r-- 1 jom2ot mkgroup-l-d 28 May 31 14:40 hello.h drwxr-xr-x+ 2 jom2ot mkgroup-l-d 0 May 31 14:25 parallel lrwxrwxrwx 1 jom2ot mkgroup-l-d 16 May 31 14:43 universe -> ../inc2/parallel
12.) Try Cygwin's gcc. $ gcc -Ic:/Playground/test/inc2 -o hello hello.c Succeeds.
13.) Try GNUSH's gcc. $ sh-elf-gcc -Ic:/Playground/test/inc2 -o hello hello.c In file included from hello.c:2: c:/Playground/test/inc2/hello.h:1:28: universe/world.h: No such file or directory Fails!
That means, even if only using c:/ paths would be an acceptable workaround this technique fails once there are symbolic links involved. IMHO even more proof that there is something severly wrong with GNUSH.
The problem is reproducible with GNUSH v0501 as well as v0403.
Sadly, I am not allowed to use Linux.
Thank you for giving away the KPIT GNU tools and support for free.
Best Regards Mark Jonas
