I'm running on SPARC-10/SunOS 4.1.3, trying to build and install gcc 2.4.3.
I executed the following configure command:

    configure --target=sparc-sun-sunos4.1 \
	--prefix=/home/ausable/software \
	--exec-prefix=/home/ausable/software

and wound up with the first action in the make as (I'd already built the
stage1 compiler):

    stage1/xgcc -Bstage1/  -DIN_GCC   -g     -I. -I. -I./config \
	-DGCC_INCLUDE_DIR=\"/home/ausable/software/lib/gcc-lib/sparc-sun-sunos4.1/2.4.3/include\" \
	-DGPLUSPLUS_INCLUDE_DIR=\"/home/ausable/software/lib/g++-include\" \
	-DLOCAL_INCLUDE_DIR=\"/usr/local/include\" \
	-DCROSS_INCLUDE_DIR=\"/home/ausable/software/lib/gcc-lib/sparc-sun-sunos4.1/2.4.3/sys-include\" \
	-DTOOL_INCLUDE_DIR=\"/home/ausable/software/sparc-sun-sunos4.1/include\" \
	-DTOOLDIR=\"/home/ausable/software/sparc-sun-sunos4.1/\" \
	-c `echo ./cccp.c | sed 's,^\./,,'`

Note that TOOLDIR is defined as /home/ausable/software/sparc-sun-sunos4.1.
In the past (2.3.3 and before), everything sort of wound up in
/home/ausable/software/lib if I simply set the prefix argument to configure
to /home/ausable/software.

If I configure with:

    configure --target=sparc-sun-sunos4.1 \
	--prefix=/home/ausable/software \
	--exec-prefix=/home/ausable/software/lib

TOOLDIR is set properly, but now there are several occurrences of
/home/ausable/software/lib/lib in the other defines:

    stage1/xgcc -Bstage1/  -DIN_GCC   -g     -I. -I. -I./config \
	-DGCC_INCLUDE_DIR=\"/home/ausable/software/lib/lib/gcc-lib/sparc-sun-sunos4.1/2.4.3/include\" \
	-DGPLUSPLUS_INCLUDE_DIR=\"/home/ausable/software/lib/lib/g++-include\" \
	-DLOCAL_INCLUDE_DIR=\"/usr/local/include\" \
	-DCROSS_INCLUDE_DIR=\"/home/ausable/software/lib/lib/gcc-lib/sparc-sun-sunos4.1/2.4.3/sys-include\" \
	-DTOOL_INCLUDE_DIR=\"/home/ausable/software/lib/sparc-sun-sunos4.1/include\" \
	-DTOOLDIR=\"/home/ausable/software/lib/sparc-sun-sunos4.1/\" \
	-c `echo ./cccp.c | sed 's,^\./,,'`

It seems to me that there is a buglet somewhere in the configure process,
but on the possibility that I'm doing something wrong, I've sent this to
both help-gcc and bug-gcc. I apologize to those of you who will see this
note twice as a result.

My workaround was to use the first configure command and modify the tooldir
definition in the generated Makefile to be

    tooldir = $(exec_prefix)/lib/$(target)

I'm not sure if that's necessarily the correct "fix", but it served my
purposes.
