Unfortunately this isn't sufficient. The default compiler on Debian woody calls itself 2.95.4. So this check isn't sufficient. However, building current cvs with -DGCC_VER_3 does repair the link problems I was seeing 'out of the box' with 2.95.4. Just so we're all on the same page, this particular trouble looks like:

make[1]: Entering directory `/home/giles/projects/ghostscript/omni/XMLParser'
c++ -o parser MyErrorHandler.o OmniDomParser.o Main.o -L .. -lomni -lxml -L/usr/lib -rdynamic -lgmodule -lglib -ldl
../libomni.so: undefined reference to `getEnumeration__Q312OmniPDCProxy38getCurrentResolution__12OmniPDCProxy.0_22OmniPDCProxyResolution.987'
[...and many similar undefined references]

Building with DEBUG=1 also remedied this.

The (__GNUC__ > 3) check does work with gcc-3.0, but there appear to additional source gotchas:

g++-3.0 -Wall -fPIC -rdynamic -O3  -DRETAIL=1  -I . -I hppcl3 -I/usr/include/glib-1.2 -I/usr/lib/glib/include -c DeviceBlitter.cpp
In file included from DeviceBlitter.cpp:19:
Device.hpp:141: type specifier omitted for parameter
Device.hpp:141: parse error before `)' token
make: *** [DeviceBlitter.o] Error 1

I hope we can get this cleared up and building more portably soon.

Cheers,
