# LIBTOOL ISSUES
#
# Most of the libraries and programs are linked using the dynamic linker
# We default to using the dynamic linker and have a special link macros for
# using the static linker.
#
# Also libtool looks like the future in cross platform shared object compile
# and linking, but unfortunately it does not yet work for us, as a
# libtool gcc -o $(BIN)/fred fred.o libzzz.la
# command will generate incorrect relative addresses in the wrapper script in
# $(BIN)/fred as it required the exe file fred to be in the directory from
# which the command is run from.
# One other issue is that libtool puts a -DPIC onto the compile line.  While
# nice it conflicts with a struct in the file qli/format.h
# MOD 26-July-2001.

# LINKER COMMANDS
# they are candidates to go to make.defaults and make this file make.defaults.in
# if we decide to support different linkers directly in our build process. 
# Alternatively we may use libtool here.

# Here we have definitions for using the preprocessor.

# The GPRE_FLAGS is overwritten in Makefile.in.jrd Makefile.in.gpre and
# since they do something extra to allow the boot build to work.
#
# One other point is that sometimes a failure in compile with gpre does not
# result in an error being generated.  The generated source file still
# compiles and throws the make off the path.
#
# This bit of code is part of unfinished bit to let make determine if
# gpre gpre_static or gpre_boot should be used based on which ones exist.
