CROSS COMPILE: gcc 2.95.3 is ok ... but libstc++-2.90.8 fails ... nan()

[James Don]

Hi all,

I am currently working on compiling gcc-2.95.3 with glibc-2.2.5 ... This
works fine (meaning it compiles) for my target powerpc-linux ... 

But I die compiling libstdc++-2.90.8 with the below build script ... its
seems to have problems with nan() in libstdc++ being different than that in
glibc ... I am really stuck on what I am doing wrong ... I assume my glibc
version is wrong ... or I am simply building things incorrectly ...

Any tips would be great ... I am hoping to clean up this script when it
works and send it out to other ppc embedded developers requiring STL on
there targets ...

Thanks in advance,

Jim

Ps I have modified my script in other ways to get other problems ... like no
target in libstc++ for "make all-target" ... I am really stuck I think and
need some real solid advice ... besides download an rpm ;-)
