build fails on cygwin

[Paul Kienzle]

Compile GiNaC 1.2.0 on cygwin using gcc 3.2 20020927:

ginac/remember.cpp
	table_size = 1 << log2(s);

The compiler doesn't like the mixture of integer and double
on operator<<.  I used int(log2(s)).


If this is also the place to report CLN build issues,
version 1.1.5 */Makefile.in do not include
	LDFLAGS = @LDFLAGS@
so it couldn't find my version of libgmp.a.
