(Which problem is not described in this message and the stated URL is 
invalid.  Searching suggests it is related to MAIN__.)

No.  Only R.bin is in any way similar to the embedded examples: tcltk is 
run from R, not R from tcltk.

Solaris 8, gcc 3.4.3 works for me.

Note that MAIN__ is defined in Rmain.c, and that is part of R.bin and not 
libR.so.  You could try copying it is to Rtest.c to see if this helps.

What you have not told us is the Fortran that you are using.  That is 
likely to be the clue.  Try a current gcc AND g77 -- gcc is a Compiler 
Collection, not just a C compiler.
