Hi. 

I'm trying to build gcc 5.2.1 on AIX (7.1).

I manage to build gcc using ./configure .... && make.

But I cannot build-it using --enable-bootstrap configure option and then 
"make bootstrap-lean". The build process always stop with this kind of 
errors (lots of them):

The ./configure looks like this:

cd gcc-build-%{version}

CXX=g++ \

CFLAGS='-O2 -I/opt/freeware/include' \

LDFLAGS="-L/opt/freeware/lib -Wl,-bbigtoc 
- -Wl,-blibpath:/opt/freeware/lib/gcc/%{buildhost}/%{version}:/opt/freeware/lib:/usr/lib:/lib 
- -Wl,-bmaxdata:0x80000000" \
../%{name}-%{version}-%{DATE}/configure \

	--disable-nls \
	--enable-decimal-float=dpd \
	--build=powerpc-ibm-aix7.2.0.0 \
	--enable-checking=release \
	--enable-bootstrap

and "make" like this:

gmake -j 4 \
    BOOT_CFLAGS='-O2 -I/opt/freeware/include' \
    CFLAGS='-O2 -I/opt/freeware/include' \
    CXXFLAGS='-O2 -I/opt/freeware/include' \

    bootstrap-lean

So, can anyone help with the above errors? Thank you.


Sincerely,
