I thought it might be because -I. precedes -I../libdecnumber, so I moved -I. to the end of the list of options in <source dir>/gcc/Makefile but the result was the same. Then I fiddled with the above command line and found out that <build dir>/prev-gcc/xgcc -B/home/angel/software/gcc/build/./prev-gcc/ -B/home/angel/installed_software/gcc/powerpc-unknown-linux-gnu/bin/ -W -Wall -pedantic -I../libdecnumber -I. ../../source/unpacked/gcc/dbgcnt.c still includes <build dir>/../libdecnumber/config.h instead of <build dir>/config.h. The only way to include <build dir>/config.h that I found was by removing -I../libdecnumber from command line but I guess I should not do this. So, what else could I try? Angel Tsankov
