All,

Has anyone been able to build the CVS LIBC using GCC 3.1 sucessfully?  The
list of files that need to be modified is included at the end of this email
in order to get GCC 3.1 to build the CVS LIBC source code.

The following is what the SIGSEV I get, I will have another look in the
morning.

So far the files that are needed to be modified by adding a type cast for
one or more function parameters, the files are:-
src\libc\ansi\stdio\fprintf.c
src\libc\ansi\stdio\fscanf.c
src\libc\ansi\stdio\printf.c
src\libc\ansi\stdio\remove.c
src\libc\compat\ioctl\ioctl.c
src\libc\compat\stdio\vscanf.c
src\libc\compat\stdio\vsscanf.c
src\libc\compat\time\select.c
src\libc\compat\unistd\_irdlink.c
src\libc\compat\unistd\fchown.c
src\libc\compat\unistd\llseek.c
src\libc\dos\io\_close.c
src\libc\dos\io\_creat_n.c
src\libc\dos\io\_open.c
src\libc\dos\io\_read.c
src\libc\dos\io\_write.c
src\libc\posix\fcntl\fcntl.c
src\libc\posix\sys\stat\fstat.c
src\libc\posix\sys\stat\lstat.c
src\libc\posix\unistd\link.c
src\libc\posix\unistd\lseek.c
src\libc\posix\unistd\write.c

The following file needs a small code change in order to build:-
src\libc\posix\unistd\confstr.c

There are two code changes to fix this  are:-
a)   out_len = 1;
      memcpy (buf, "\0", out_len);
      break;
b) out_len = snprintf(buf, len, "%s", "");

The easier change is option b.

Regards,
Andrew
