Building a Fortran Cross Compiler with Gcc-2.95.3

[<aaronchiles at cox dot net>]

I having problems building a fortran cross compiler.  I've tried several different versions, configuration, etc. and I'm not having any luck.  Most want to know what my procedure is before they can diagnose my problem so I'll just go though the procees.  First I download gcc-2.95.3 and binutils02.14 and make an empty target directory all in the same level for this it will be /opt/src/xcomp/.

Next I configure the binutilites with the following configuration typing: configure --host=sparc-sun-solaris2.9 --target=powerpc-wrs-vxworks --with-headers=/opt/wind/target/h --with-libs=/opt/wind/target/lib --prefix=/opt/src/xcomp/target --enable-threads=vxworks

After its configures I edit /opt/src/xcomp/binutils-2.14/gas/as.c adding line 38
37 #define COMMON
38 #define BFD_VERSION_STRING "2.14"
39
40 #include "as.h"

I type 'make' and then 'make install'.  And it install the assembler, loader, etc.

Then I 'cd' to /opt/src/xcomp/gcc-2.95.3 to configure the gcc.  (I chose not to create a build directory because I get the same results and felt I might as well leave it all in the same directory)  For the gcc configuration I give the following command at the prompt.  
/opt/src/xcomp/gcc-2.95.3> configure --host=sparc-sun-solaris2.9 --target=powerpc-wrs-vxworks --with-headers=/opt/wind/target/h --with-libs=/opt/wind/target/lib --prefix=/opt/src/xcomp/target --enable-threads=vxworks --enable-languages=f77

When the configure finishes I edit the Makefile to such that its add a flag to the CFLAGS.  
CFLAGS = -g 02 -DCPU=PPC604

Then I type ?make? and it begins to build.   After its stop I then type ?make install? and it finishes but I believed stopped in the middle.  I scroll up and find a message that:

checking for a BSD compatible install? ../../install-sh ?c
checking whether make sets ${MAKE}? yes
checking how to run C preprocessor? /opt/src/gcc-2.95.3/gcc/xgcc ?B/usr/include/sys/ 
	-B/opt/src/xcomp/gcc-2.95.3/gcc/ -B/opt/src/xcomp/target/powerpc-wrs-vxworks/bin/ -E
checking for stdio.h? no
configure: error: Can?t find stdio.h.
You mus have a usable C system for the target already installed, at least including headers and, preferably, the library, before you can configure the G77 runtime system. If necessary install gcc now with ?LANGUAGES=c? then the target library, then build with ?LANGUAGES=f77?. 

I?ve tried configuring with out enabling f77 and it seems the C will not install.
I ?cd? to /gcc/ and try to ?make install? there. It seems to build ok but I don?t know if it installed fine?so I do a ?make ?n install LANGUAGES =c?.   

I receive the following set of errors:

I think if I can get past this I may be able to accomplish building the Fortran cross compiler.  Anyone have any Ideas?
