	* install.texi: Mention HP-UX sed problems, needing GNU make for
 	srcdir != builddir.

  To enable debugging, you must configure GNU CC with the @samp{--with-gnu-as}
  option before building.
  
+ When building gcc on a hppa*-*-hpux10 platform, the @samp{fixincludes} step
+ (which involves running a @code{sed} script) fails because of a bug in
+ the vendor's implementation of @code{sed}.  Currently the only known
+ workaround is to install GNU @code{sed} before building GCC@.  The file
+ @file{sed-2.05.bin.hpux10} available from mirrors of the GNU
+ distribution area is a precompiled binary for that platform.

  This port is very preliminary and has many known bugs.  We hope to
  have a higher-quality port for this machine soon.

  The directory you specify with @samp{--srcdir} need not be the same
  as the one that @code{configure} is found in.
+ 
+ It is normally necessary to to use GNU @code{make} to build GCC in a
+ directory different from the source code directory since other
+ @code{make}s typically don't use the same machanism for finding source
+ files.

  Now, you can run @code{make} in that directory.  You need not repeat the

	* config-lang.in: Remove the messages about possible build
	problems -- now either irrelevant to moved to manual.
