glibc-2.3.3 & scripts/check-c++-types.sh

[Ankur Sheth]

Hi,
   Using crosstool-0.28-rc37 I built a gcc-3.3.4-glibc-2.3.3 toolchain for
ppc750.  While running the regression tests for the toolchain
scripts/check-c++-types.sh failed.  On investigating more I discovered that
the test is invoked from glibc-2.3.3/Makefile in the following manner :

$(objpfx)c++-types-check.out:
scripts/data/c++-types-$(config-machine)-$(config-os).data
 scripts/check-c++-types.sh $^ $(CXX) $(filter-out -std=gnu99,$(CFLAGS))
$(CPPFLAGS) > $@

build-glibc/config.make lists CC, CXX & HOST_CC as follows 

# Build tools 
CC = powerpc-750-linux-gnu-gcc
CXX = g++
BUILD_CC = gcc

and hence in the above rule CXX gets translated to g++ and not
powerpc-750-linux-gnu-g++.  When run as g++ the test fails and passes when
run with powerpc-750-linux-gnu-g++.

  After applying the following patch and I was able to build the tool-chain
successfully.  I haven't been able to check if the test passes or not (I
expect it to pass since config.make now lists CXX =
powerpc-750-linux-gnu-g++).
