@c The version number appears five times more in this file.
When @samp{-pedantic-errors} is specified, GCC will incorrectly give
an error message when a function name is specified in an expression
involving the comma operator.

-Loop unrolling doesn't work properly for certain C++ programs. This is
-a bug in the C++ front end. It sometimes emits incorrect debug info, and
-the loop unrolling code is unable to recover from this error.

@node Installation Problems
The solution is not to use such a directory for building GCC.
-@item
-In previous versions of GCC, the @code{gcc} driver program looked for
-@code{as} and @code{ld} in various places; for example, in files
-beginning with @file{/usr/local/lib/gcc-}. GCC version 2 looks for
-them in the directory
-@file{/usr/local/lib/gcc-lib/@var{target}/@var{version}}.
-
-Thus, to use a version of @code{as} or @code{ld} that is not the system
-default, for example @code{gas} or GNU @code{ld}, you must put them in
-that directory (or make links to them from that directory).

Some commands executed when making the compiler may fail (return a
non-zero status) and be ignored by @code{make}. These failures, which
It would be nice to extend GAS to produce the gp tables, but they are
optional, and there should not be a warning about their absence.
-@item
-In Ultrix 4.0 on the MIPS machine, @file{stdio.h} does not work with GNU
-CC at all unless it has been fixed with @code{fixincludes}. This causes
-problems in building GCC. Once GCC is installed, the problems go
-away.
-
-To work around this problem, when making the stage 1 compiler, specify
-this option to Make:
-
-@example
-GCC_FOR_TARGET="./xgcc -B./ -I./include"
-@end example
-
-When making stage 2 and stage 3, specify this option:
-
-@example
-CFLAGS="-g -I./include"
-@end example

Users have reported some problems with version 2.0 of the MIPS
compiler tools that were shipped with Ultrix 4.1. Version 2.10
