If you have two libraries which depend on each other, you really have
one library and should build them as one library.  Or build them as
objects, not libraries.  In general, two-way dependencies indicate
that you haven't organized your libraries very well.

However, recent linkers have options -( and -) to "group" libraries
for such cases.  You can also create a "group" library which has a
library filename (bc.a) but has as its contents a link script (text
file) which defines a grouped list of libraries.

gcc a.c -( -lb -lc -) -o a.exe

Might need quotes around those, depending on which shell you use.
