Re: GNU make 3.99.91 release candidate is available

I've done some testing and bug fixing using the Solaris build service,
thanks very much Dago!

Investigating this I've discovered the problem.  The Guile library
provided on these systems was compiled with GCC, not the Sun Studio
compilers.

As a result, the guile-pkg command that configure uses to determine what
the linker flags should be to link with Guile are returning GCC linker
flags.  In particular, the "-pthreads" flag generated here:

  $ pkg-config --cflags guile-2.0
  -D_REENTRANT -pthreads -I/opt/csw/include/guile/2.0 -I/opt/csw/include 

is a GCC flag that is not valid to the Sun Studio linker, so it
interprets that flag as if it were:

 -p -t -h -r -e -a -d -s

Hence, the error about the -h flag.

I don't actually have any good ideas about how to fix this problem.
Most likely this is something that needs to be raised with the autoconf,
pkgconfig, and/or Guile folks.

In the meantime if you compile make with GCC instead of Sun Studio it
works properly with Guile.  You could also supply the GUILE_CFLAGS
variable to configure to override the pkg-config output.  Of course you
could also build Guile with Sun Studio and that would likely work as
well (but now perhaps you wouldn't be able to compile with GCC).

I also found that for some reason configure is determining that libc
contains a GNU gettext implementation which is clearly not true, and
thus leaving off the -lintl library causing link errors.

Finally, because the GNU libraries are not installed in the standard
locations you need to add "LDFLAGS=-R/opt/csw/lib" to the configure line
so that GNU make will know where to look for the guile, etc. libraries
at runtime.  Using LD_LIBRARY_FLAGS is not a good idea because it will
break other programs.

After working around these issues and my regression test fixes (to be
pushed shortly), I am able to build on Solaris 11 with the Sun Studio
compiler and get 100% test coverage, including Guile support:
