Hi Paul,
I have included your suggested change in the development version.
You mention that you had to apply the mods reported by Jonathan Hays,
but as far as I know, his changes were already included in the latest
versions. Could you clarify this point?

I used Makesolarisegcs.mk found in the $ROOTSYS/src dir and I followed Jonathan Hays' outline (roottalk 16 Dec 1998) which describes the code modifications. This worked well until the make of root.exe which failed due to missing sincos in the linking. Adding -lsunmath also failed because the linker could not find it( and I could not either).
