I've built an arm-elf cross-compiler built and hosted on DJGPP. The tools 
are installed in 'C:\armtools' and work correctly when run from other 
directories on the C drive.

However, there is a problem if I try to run the compilers while in a 
directory on another disk. In this case, no path seems to be found to the 
'crt0.o' file for linking.

The DJGPP environment variable is pointing to a file containing the 
following:

-------------------
DJDIR=%:/>DJGPP%

+USER=dosuser
+LFN=y

COMPILER_PATH=%DJDIR%\arm-elf\bin\
GCC_EXEC_PREFIX=%DJDIR%\lib\gcc-lib\

C_INCLUDE_PATH=%/>;C_INCLUDE_PATH%%DJDIR%/include
LIBRARY_PATH=%/>;LIBRARY_PATH%%DJDIR%/lib
-------------------

Without setting GCC_EXEC_PREFIX as shown, the compiler uses its built-in 
specs and the CPP seems to be called recursively with a ever increasing 
(and repeated) list of options. Again, this only happens when calling the 
compilers from a drive other than the C drive on which they are installed 
which I assume is due to the use of relative paths.

Is there a way to allow the 'crt0.o' file to be found correctly, or 
perhaps this is due to a mistake in the configuration used to build the 
compilers (shown below)?

Any help would be appreciated!

Compiler configuration:

configure  --verbose \
           --disable-nls \
           --with-gnu-as \
           --with-gnu-ld        \
           --target=arm-elf \
           --disable-shared \
           --host=i386-pc-msdosdjgpp \
           --with-cpu=strongarm \
           --with-newlib \
           --with-local-prefix=/armtools/arm-elf \
           --with-gxx-include-dir=/armtools/lang/cxx \
           --prefix=/armtools
