6.3.2 build, more questions

Okay, most of my compilation problems are path related.
Now, when running configure, the conftest program refuses to
compile due to a library path issue.  The system I use has it's
gnu 'things' in assorted places which I did not arrange, so I must
adapt to their locations.  How do I specify the -I and -L paths
for gcc?  I've tried adjusting the template file's SRCH_LIB, but
this is only a guess on my part - I've not found any documentation
for the template files.

    CC:gcc
    AROPT:crs
    CFLAGS:
    SHARED_LIB:-fPIC
    ALL:
    SRCH_INC:
    SRCH_LIB:/opt/FSFutil/lib/gcc-lib/sparc-sun-solaris2.4/2.7.2
    USE_LOCALE:no
    DLSUFFIX:.so
    YFLAGS:-d
    YACC:

I've also tried the command line options:

./configure --with-template=sparc_solaris-gcc \
    --with-includes='where gcc's includes are' \
    --with-libs='where gcc's libs are'

substituting the text accordingly.  What is the proper method to inform
configure of where the libraries and include files are?

Thanks for bearing with me.
