 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.
