[Bug c/42047] New: Failed build genmodes

[monaka at monami-software dot com]

I failed to build gcc with configuration follows:

../gcc/configure --target=sh-elf --host=i386-pc-mingw32
--build=i686-apple-darwin10 --enable-languages=c --with-gmp=/opt/MinGW
--with-mpfr=/opt/MinGW


I think genmodes should be built on build environment, but there seems it was
built with include pathes for "host". 

gcc -c -DIN_GCC -DCROSS_DIRECTORY_STRUCTURE   -DGENERATOR_FILE -I. -Ibuild
-I../../gcc/gcc -I../../gcc/gcc/build -I../../gcc/gcc/../include -I./../intl
-I../../gcc/gcc/../libcpp/include -I/opt/MinGW/include -I/opt/MinGW/include
-I../../gcc/gcc/../libdecnumber -I../../gcc/gcc/../libdecnumber/dpd
-I../libdecnumber     \
                -o build/genmodes.o ../../gcc/gcc/genmodes.c
In file included from ../../gcc/gcc/system.h:42,
                 from ../../gcc/gcc/genmodes.c:22:

I think this issue is caused by "BUILD_CPPFLAGS=$(ALL_CPPFLAGS)" in Makefile.in


I got sources from git://git.infradead.org/gcc.git, not official svn. But this
issue will be occured with official releases.

Oh I see why this works for me, I install gmp/mpfr in the sysroot and I had
used the sysroot so I don't need to supply --with-gmp/--with-mpfr.

Looks like we need a new variable for build includes (that is BUILD_INCLUDES
which does not include GMPINC, PPLINC, DECNUMINC, LIBELFINC, or CLOOGINC).

I think, too. I've built successful with my patch. (I don't send my patch
because it is half-finished.)
