Solaris 10: wchar_iso.h vs cwchar

[Maciej Bliziński]

Here's an update: When building with gmp/mpc/mpfr sources inside gcc
sources, I get this error message:

libtool: compile:  /opt/csw/gcc3/bin/gcc -DHAVE_CONFIG_H -I.
-I../../../gcc-4.6.1/mpc/src -I.. -I/home/maciej/src/gcc-objdir/./gmp

As a separate effort, I have built gcc again, using the OpenCSW build
system, with less options and simplified environment. There's a new
problem I ran into.  Here's the error message I'm getting from
checkpkg:

 * libgcc_s.so.1 could not be resolved for opt/csw/lib/libstdc++.so.6.0.16,
   with rpath ('/usr/lib/$ISALIST', '/usr/lib', '/lib/$ISALIST', '/lib'),

Looking at the binary:

The library has in fact libgcc_s.so.1 in NEEDED, but does not have RPATH set.

What's missing in the linker invocation, is "-R/opt/csw/lib".  I've
found this text in the configuration docs[1]:

--with-boot-ldflags=flags
This option may be used to set linker flags to be used when linking
stage 2 and later when bootstrapping GCC. If neither –with-boot-libs
nor –with-host-libstdcxx is set to a value, then the default is
`-static-libstdc++ -static-libgcc'.

I've tried setting: --with-boot-ldflags="-R/opt/csw/lib", and
recompiling gcc from scratch, but it didn't help.  I'll try exporting
LDFLAGS with -R/opt/csw/lib.
