While cross building gcc-4.1.0 rc2 for sparc-sun-solaris2.7 on FC4, this error
is being issued:

...
checking for enabled iconv specializations... yes
checking for shared libgcc... yes
/users/rtems/src/rpms/BUILD/local-sparc-sun-solaris2.7-gcc-4.1.0_20060223/gcc-4.1.0/libstdc++-v3/configure:
line 87719: test: -lt: unary operator expected
checking for size_t as unsigned int... yes
checking for ptrdiff_t as int... yes
...

This is a sysroot'ed build, using vanilla FSF-binutils-2.16.1
config.log doesn't contain any indication on what might be going wrong.

  elif test $glibcxx_gnu_ld_version -lt $glibcxx_min_gnu_ld_version ; then

What options are you using to bootstrap with?

glibcxx_gnu_ld_version is only set when building natively, but used when
--with-gnu-ld which implies --enable-symvers=gnu.

So what to do? Moving GLIBCXX_CHECK_LINKER_FEATURES out of the "native"
if-clause?

This is the bug. Unfortunately, GLIBCXX_CHECK_LINKER_FEATURES is a native-only
test. 

However, even if not native, if using GNU ld one should be able to get the
version  and thus set glibcxx_gnu_ld_version. I suppose that is the right way
to fix this.

Could you explain why it is native-only? 

AFAIS, it tries to run the linker, which is a build-host tool at this point.

------- Comment #7 from bkoz at gcc dot gnu dot org  2006-03-17 18:31 -------

linking tests are native only, because finding all the support objects needed
for all the various platforms (crt.o, etc.) is hard. At least, this is the
traditional objection.

fixing glibcxx_gnu_ld_version still seems possible, see earlier comment.
Suggest you try this approach...
