I have just investigated the possibility of linking libgcc_s statically,
in order to remove this dependency, but apparently this is not advisable
because (a) the dynamic library is required for proper exception handling
in a C++ context, and (b) the -static-libgcc option works only if using
the gnu linker (which we don't).

So the clean way for you is to get libgcc_s.so.1, e.g. from sunfreeware.com
ftp://ftp.sunfreeware.com/pub/freeware/sparc/10/libgcc-3.4.6-sol10-sparc-local.gz
If you can't/don't want to install it in the standard location, you can
just put libgcc_s.so.1 to <eclipsedir>/lib/sparc_sunos5

I will also see to add this to the standard eclipse distribution.

What's relevant are the libraries it links to.
Go to lib/sparc_sunos5 and use ldd:

% ldd eclipse.exe
         libeclipse.so =>         ./libeclipse.so
         libgmp.so.3 =>   ./libgmp.so.3
         libsocket.so.1 =>        /usr/lib/libsocket.so.1
         libnsl.so.1 =>   /usr/lib/libnsl.so.1
         libdl.so.1 =>    /usr/lib/libdl.so.1
         libm.so.1 =>     /usr/lib/libm.so.1
         libc.so.1 =>     /usr/lib/libc.so.1
         libgcc_s.so.1 =>         /usr/local/lib/libgcc_s.so.1
         libmp.so.2 =>    /usr/lib/libmp.so.2
         /usr/platform/SUNW,UltraAX-i2/lib/libc_psr.so.1
% ldd libeclipse.so
         libgmp.so.3 =>   ./libgmp.so.3
         libsocket.so.1 =>        /usr/lib/libsocket.so.1
         libnsl.so.1 =>   /usr/lib/libnsl.so.1
         libdl.so.1 =>    /usr/lib/libdl.so.1
         libm.so.1 =>     /usr/lib/libm.so.1
         libc.so.1 =>     /usr/lib/libc.so.1
         libgcc_s.so.1 =>         /usr/local/lib/libgcc_s.so.1
         libmp.so.2 =>    /usr/lib/libmp.so.2
         /usr/platform/SUNW,UltraAX-i2/lib/libc_psr.so.1

Only libgmp, but that's already part of the distribution.
