-Various early versions of each release of the IBM XLC compiler will not
-bootstrap GNU CC.  Symptoms include differences between the stage2 and
-stage3 object files, and errors when compiling @file{libgcc.a} or
-@file{enquire}.  Known problematic releases include: xlc-1.2.1.8,
-xlc-1.3.0.0 (distributed with AIX 3.2.5), and xlc-1.3.0.19.  Both
-xlc-1.2.1.28 and xlc-1.3.0.24 (PTF 432238) are known to produce working
-versions of GNU CC, but most other recent releases correctly bootstrap
-GNU CC.
-
-Release 4.3.0 of AIX and ones prior to AIX 3.2.4 include a version of
-the IBM assembler which does not accept debugging directives: assembler
-updates are available as PTFs.  Also, if you are using AIX 3.2.5 or
-greater and the GNU assembler, you must have a version modified after
-October 16th, 1995 in order for the GNU C compiler to build.  See the
-file @file{README.RS6000} for more details on any of these problems.
-
-GNU CC does not yet support the 64-bit PowerPC instructions.
-
-Objective C does not work on this architecture because it makes assumptions
-that are incompatible with the calling conventions.
-
-AIX on the RS/6000 provides support (NLS) for environments outside of
-the United States.  Compilers and assemblers use NLS to support
-locale-specific representations of various objects including
-floating-point numbers ("." vs "," for separating decimal fractions).
-There have been problems reported where the library linked with GNU CC
-does not produce the same floating-point formats that the assembler
-accepts.  If you have this problem, set the LANG environment variable to
-"C" or "En_US".
-
-Due to changes in the way that GNU CC invokes the binder (linker) for AIX
-4.1, you may now receive warnings of duplicate symbols from the link step
-that were not reported before.  The assembly files generated by GNU CC for
-AIX have always included multiple symbol definitions for certain global
-variable and function declarations in the original program.  The warnings
-should not prevent the linker from producing a correct library or runnable
-executable.
-
-By default, AIX 4.1 produces code that can be used on either Power or
-PowerPC processors.
-
-You can specify a default version for the @samp{-mcpu=}@var{cpu_type}
-switch by using the configure option @samp{--with-cpu-}@var{cpu_type}.
