Symbol versioning question

[Steve Dunham]

When I updated the glibc in Sparc version of Debian, I found that I
could no longer link (at compile time) programs against a couple of
the shared libraries on the system.  A typical example is that it
claims it can't find the symbol "_popen@GLIBC_2.0" referenced by
libgpm.so, where libc contains both GLIBC_2.1 and GLIBC_2.0 versions
of the symbol.

Run time linking works fine.

My conclusion is that the compile time linker can't see older versions
of the symbols.  Is this an intended feature?
