Error compiling gcc/g++ 4.1.1 on AIX 5.2

[Michael H.]

Hi,

I'm trying to compile gcc/g++ 4.1.1 on AIX 5.2. I called configure
with parameters --disable-aix64 --disable-nls --enable-languages=c++.
At first everything seams to work fine, but then I get lots of errors
while compiling <builddir>/gcc/insn-conditions.c, like

<srcdir>/gcc/config/rs6000.md:4695: error 'TARGET_POWER2' undeclared
here (not in a function)
<srcdir>/gcc/config/rs6000.md:4695: error 'TARGET_HARD_FLOAT'
undeclared here (not in a function)

followed by

<srcdir>/gcc/config/rs6000.md:4696: warning: missing initializer
<srcdir>/gcc/config/rs6000.md:4696: warning: (near initialization for
'insn_conditions[1].value')

Any ideas what's going wrong here?

Michael
