Hi,
We're trying to build the latest Firebird 1.5.2 SuperServer source for
the Mac (because there isn't a SuperServer version for the Mac on the
Firebird website). However the build dies with the following error:

cc -DSUPERCLIENT -D_THREAD_SAFE -I../src/include/gen

ld: unknown flag: --version-script
make[2]: *** [../gen/firebird/intl/libfbintl.dylib] Error 1
make[1]: *** [intl] Error 2
make: *** [firebird] Error 2

To configure the build, we used: ./configure --enable-superserver

It seems that the culprit is "ld: unknown flag: --version-script".
What is this step attempting to do and how can we resolve it on the
Mac?

Thanks
Phil
