# The -I- option is only needed for 32 bit builds on x86_64.  It provides a feature that is not present in
# -iquote - namely -I- disables the ability to search the current directory for include files.  This is needed
# when compiling something in sr_port which includes a file that is in both sr_port and the architecture specific
# sr_386.  We don't want the sr_port version.  An example is sr_port/code_gen.c which includes emit_code.h.
# emit_code.h is found in both sr_port and sr_i386.  Using -I- will find the sr_i386 version, but without it the
# sr_port version is used. SLJ 2010.03.31
