###
### This is a template compound command to build an executable binary with
### an internal symbol table.
### This process is tricky.  We first link all objects including a tentative
### empty symbol table, then get a tentative list of symbols from the resulting
### binary ($@tmp0).  Next, we re-link all objects, but this time with the
### symbol table just created ($tmp@1).  The set of symbols should be the same,
### but the corresponding addresses would be changed due to the difference on
### the size of symbol tables.  So we create the symbol table and re-create the
### objects once again.  Finally, we check the symbol table embedded in the
### final binaryis consistent with the binary itself; otherwise the process is
### terminated.
###
### To minimize the overhead of creating symbol tables, the autoconf switch
### --enable-symtable takes an argument so that the symbol table can be created
### on a per application basis: unless the argument is set to "all", the symbol
### table is created only when a shell (environment) variable "MAKE_SYMTABLE" is
### set to a non-null value in the rule to build the executable binary.
###
### Each Makefile.in that uses this macro is expected to define "LIBS" and
### "NOSYMLIBS"; the former includes libisc with an empty symbol table, and
### the latter includes libisc without the definition of a symbol table.
### The rule to make the executable binary will look like this
### binary@EXEEXT@: ${OBJS}
###     #export MAKE_SYMTABLE="yes"; \  <- enable if symtable is always needed
###	export BASEOBJS="${OBJS}"; \
###	${FINALBUILDCMD}
###
### Normally, ${LIBS} includes all necessary libraries to build the binary;
### there are some exceptions however, where the rule lists some of the
### necessary libraries explicitly in addition to (or instead of) ${LIBS},
### like this:
### binary@EXEEXT@: ${OBJS}
###     cc -o $@ ${OBJS} ${OTHERLIB1} ${OTHERLIB2} ${lIBS}
### in order to modify such a rule to use this compound command, a separate
### variable "LIBS0" should be deinfed for the explicitly listed libraries,
### while making sure ${LIBS} still includes libisc.  So the above rule would
### be modified as follows:
### binary@EXEEXT@: ${OBJS}
###	export BASEOBJS="${OBJS}"; \
###	export LIBS0="${OTHERLIB1} ${OTHERLIB2}"; \
###     ${FINALBUILDCMD}
### See bin/check/Makefile.in for a complete example of the use of LIBS0.
