 i386

>Description:
For some reason, the Makefile doesn't create the gcov-iov.h file with the 
version hex code to compile gcc4 , the GCOV_VERSION variable doesn't appear to 
be defined.

>How-To-Repeat:
# cd /usr/src/gnu/usr.bin/gcc4
# make


>Fix:
Compile the gcov-iov.c and generate manually the version file.

# cd /usr/src/gnu/dist/gcc4/gcc/   
# gcc gcov-iov.c -o gcov-iov.o
# ./gcov-iov.o `cat BASE-VER` `cat DEV-PHASE` > gcov-iov.h

/* Generated automatically by the program `./gcov-iov.o'
   from `4.1.3 (4 1) and prerelease (p)'.  */

#define GCOV_VERSION ((gcov_unsigned_t)0x34303170)  /* 401p */
