Installing GNU CC on the Sun
============================

   On Solaris, do not use the linker or other tools in `/usr/ucb' to
build GNU CC.  Use `/usr/ccs/bin'.

   If the assembler reports `Error: misaligned data' when bootstrapping,
you are probably using an obsolete version of the GNU assembler.
Upgrade to the latest version of GNU `binutils', or use the Solaris
assembler.

   Make sure the environment variable `FLOAT_OPTION' is not set when
you compile `libgcc.a'.  If this option were set to `f68881' when
`libgcc.a' is compiled, the resulting code would demand to be linked
with a special startup file and would not link properly without special
pains.

   There is a bug in `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 `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:

     make CC="TERMCAP=x OBJS=x LIBFUNCS=x STAGESTUFF=x cc"

   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.
