Yes, it is:

GCC/gcc/options.c: /home/roman/gccxml-0.9-cvs/GCC/gcc/opt-functions.awk
GCC/gcc/options.c: /home/roman/gccxml-0.9-cvs/GCC/gcc/optc-gen.awk
GCC/gcc/options.c: GCC/gcc/optionlist
	$(CMAKE_COMMAND) -E cmake_progress_report
/home/roman/gccxml-0.9-build/CMakeFiles $(CMAKE_PROGRESS_226)
	@$(CMAKE_COMMAND) -E cmake_echo_color --switch=$(COLOR) --blue --bold
"Generating options.c"
	cd /home/roman/gccxml-0.9-build/GCC/gcc && /usr/bin/awk -f
/home/roman/gccxml-0.9-cvs/GCC/gcc/opt-functions.awk -f
/home/roman/gccxml-0.9-cvs/GCC/gcc/optc-gen.awk -v
header_name="config.h\ system.h\ coretypes.h\ tm.h" < optionlist >
options.c
