Uh, works, kind of...
| build/src/library/eda/src $ f77 -o eda.so -bM:SRE -bexpall -bnoentry line.o smooth.o
| ld: 0711-317 ERROR: Undefined symbol: .rsort
| ld: 0711-345 Use the -bloadmap or -bnoquiet option to obtain more

The problem is that rsort is defined in sort.c. So I put all the R
files in src/main into a library:
| build/src/main $ ar cr libR.a *.o
And run the linker again:
| build/src/library/eda/src $ f77 -o eda.so -bM:SRE -bexpall -bnoentry
| line.o smooth.o -L../../../main -lR -L../../../unix -lunix
| -L../../../appl -lappl -L../../../nmath -lmath -lX11 -ldl -lblas
No error messages this time, but eda.so is big: 3020844 bytes.
Something ain't right here. There should be a way of telling the
linker to not include the libs. It should verify that all functions that
are referenced will be defined at runtime. Comments?
