I found the proper way to fix the problem and here it is.
I assume that you expand the GNUPro source code in a directory called
~/gnupro-src/

leon:/home/tsiatsis>ls -al gnupro-src
drwxr-xr-x    6 tsiatsis DomainUs     4096 Jan 16 11:28 ./
drwx------   21 tsiatsis DomainUs     4096 Jan 16 12:09 ../
drwxr-xr-x   45 tsiatsis DomainUs     4096 Jan 15 23:19 src/

In order to get the above system to build the GNUPro tools and GDB for
version 010413 you have to do the following:

1) Comment out the lines 39 and 69 from the file src/gdb/devsw.c.
Those lines have the folowing declaration:

 struct tm lt;

This declaration is useless since the variable lt is never used in the
scope of the functions that is declared. The compiler complains that
it cannot find the declaration of the type "struct tm" therefore cannot
determine the size of this type.

2) Parallel to the directory src create a directory e.g. build. So ls
in gnupro-src will give you something like the following:

leon:/home/tsiatsis>ls -al gnupro-src
drwxr-xr-x    6 tsiatsis DomainUs     4096 Jan 16 11:28 ./
drwx------   21 tsiatsis DomainUs     4096 Jan 16 12:09 ../
drwxr-xr-x   33 tsiatsis DomainUs     4096 Jan 16 11:31 build/
drwxr-xr-x   45 tsiatsis DomainUs     4096 Jan 15 23:19 src/

Change to the directory  ~/gnupro-src/build and execute the following
leon:/home/tsiatsis/gnupro-src/build>../src/configure
--host=i686-pc-linux-gnulibc2.1 --target=xscale-elf

Of course this configure command line is for the toolchain that deals
with the ELF executables. I haven't tried to produce the corresponding
toolchain for the COFF executables.

Can you please add those clarifications in the README of the GNUPro
toolchain?

The same installation instructions hold for this system but you can ommit
step 1.
