One
assumes that Sun has no interest in letting Solaris users use more
modern versions of gcc and would rather we use their own compiler.

But to properly compile on Solaris 10 with 64bit see notes from gcc.gnu.org

"i?86-*-solaris2.10
Use
this for Solaris 10 or later on x86 and x86-64 systems. This
configuration is supported by GCC 4.0 and later versions only.

It is recommended that you configure GCC to use the GNU assembler in /usr/sfw/bin/gas but the Sun linker, using the options --with-gnu-as --with-as=/usr/sfw/bin/gas --without-gnu-ld --with-ld=/usr/ccs/bin/ld"

So gcc 4.0 is the lowest version you can use for cross-compiling 32bit and 64bit applications on Solaris 10...

So we have to build our own gcc to do the firebird compilation, here's how you do it....
1. Download a copy of the gcc source (e.g. gcc-4.1.2.tar.gz) from gcc.gnu.org
2. Install gnu tar, solaris tar has problems extracting the source from the gcc tar file.
3. You will probably need to install libintl too (you can get a pre-built version of this froim www.sunfreeware.com)
4. gunzip gcc-4.1.2.tar.gz
5. /usr/local/bin/tar -xvf gcc-4.1.2.tar
6. cd gcc-4.1.2
7. mkdir objdir
8. cd objdir
9.
../configure --with-gnu-as --with-as=/usr/sfw/bin/gas --without-gnu-ld
--with-ld=/usr/ccs/bin/ld --enable-shared --enable-languages=c,c++
10. gmake
11. as root - make install
