Thanks.
In the native PS2SDK (i.e. no Linux) I detected that there are undefined
references to `__fixtfsi', `__floatsitf', `__subtf3', `__multf3',
`__extenddftf2', `__lttf2' and `__gttf2'. These are the functions for handling
"long double".
There is a fix needed for this in libgcc. I attached 2 patches to this e-mail.
There should be only one of the patches used to fix this.
The first one fixes the problem for all mips systems. The second one fixes this
only for r5900. I think it is a general problem. I assume the undefined
references could appear on all mips64 systems which are not Linux. So the first
patch should be applied.
Checking for "ac_cv_sizeof_long_double" should work on all mips systems, but I
don't know why the check was only in the mips*-linux part of the file
libgcc/config.host.
Best regards
Jürgen
