1. Edit the Makefile.
   In most cases it should suffice to set three variables: DEBUG; ASSEMBLER;
   ARCH.

2. Edit sr5sieve.h.
   Set BASE=0 for a general version of sr2sieve, BASE=2 for a fixed base 2
   version of sr2sieve (for SoB or RieselSieve projects), or BASE=5 for
   sr5sieve (for the S/R Base 5 projects).

3. Run 'make'.
   This should produce one executable: sr5sieve. Rename the executable as
   appropriate.

4. Run 'make check' (GMP libraries required).
   This will perform a test of the core modular arithmetic functions.
   If all is well then the message 'All tests passed' will appear.


Note that when compiling bsgs.c for x86 architectures with ASSEMBLER=yes,
warnings similar to the following are normal and can be ignored:
  /tmp/ccM6vgA2.s: Assembler messages:
  /tmp/ccM6vgA2.s:585: Warning: missing operand; zero assumed
