For example, @samp{sun3} stands for @samp{m68k-sun}, so
-@samp{sun3-sunos4.1} is another way to specify a Sun 3. You can also

-default to be version 4.
+@samp{sun3-sunos4.1} is another way to specify a Sun 3.
You can specify a version number after any of the system types, and some
of the CPU types. In most cases, the version is irrelevant, and will be
is usually due to bugs in @code{make}. You should either ignore this
problem, or use GNU Make.

(It is usually better to install GNU CC executables from stage 2 or 3,
since they usually run faster than the ones compiled with some other
compiler.)

-On Solaris, do not use the linker or other tools in
-@file{/usr/ucb} to build GNU CC. Use @code{/usr/ccs/bin}.
-
-If the assembler reports @samp{Error: misaligned data} when bootstrapping,
-you are probably using an obsolete version of the GNU assembler. Upgrade
-to the latest version of GNU @code{binutils}, or use the Solaris assembler.
-
-Make sure the environment variable @code{FLOAT_OPTION} is not set when
-you compile @file{libgcc.a}. If this option were set to @code{f68881}
-when @file{libgcc.a} is compiled, the resulting code would demand to be

-@cindex @code{alloca}, for SunOS
-There is a bug in @code{alloca} in certain versions of the Sun library.
-To avoid this bug, install the binaries of GNU CC that were compiled by
-GNU CC. They use @code{alloca} as a built-in function and never the one
-in the library.
-
-Some versions of the Sun compiler crash when compiling GNU CC. The
-problem is a segmentation fault in cpp. This problem seems to be due to
-the bulk of data in the environment variables. You may be able to avoid
-it by using the following command to compile GNU CC with Sun CC:
-
-@example
-make CC="TERMCAP=x OBJS=x LIBFUNCS=x STAGESTUFF=x cc"
-@end example
-
-SunOS 4.1.3 and 4.1.3_U1 have bugs that can cause intermittent core
-dumps when compiling GNU CC. A common symptom is an
-internal compiler error which does not recur if you run it again.
-To fix the problem, install Sun recommended patch 100726 (for SunOS 4.1.3)
-or 101508 (for SunOS 4.1.3_U1), or upgrade to a later SunOS release.
