You solved a part of the problem, the flag -mv850e was missing for the
linker, and now the symbols callt_... are resolved, but the symbols
___DI() and ___EI() are still unresolved :

$ make clean && make 2>&1 | tee make.out
rm -rf src/*.o
rm -rf *.i
rm -rf *.s
/tools/gnu/bin/v850-elf-gcc.exe -o src/Display.o -c -mv850e -I/tools/gnu/v850-el
f/include/ src/Display.c
/tools/gnu/bin/v850-elf-gcc.exe -o src/main.o -c -mv850e -I/tools/gnu/v850-elf/i
nclude/ src/main.c
src/main.c: In function 'main':
src/main.c:39: warning: return type of 'main' is not 'int'
/tools/gnu/bin/v850-elf-gcc.exe -o test -mv850e src/Display.o src/main.o
src/main.o: In function `_main':
main.c:(.text+0x10): undefined reference to `___DI'
main.c:(.text+0x30): undefined reference to `___EI'
src/main.o: In function `_INTP5':
main.c:(.text+0x370): undefined reference to `___EI'
collect2: ld returned 1 exit status
make: *** [test] Error 1

So I have replaced each call of __DI() and __EI() by asm("di") and
asm("ei") and the program is linked now but if anyone has an idea to
solve this problem, let me know.

Thanks again for your help
