../../gcc-trunk/gcc/gcc.c: In function 'process_command':
../../gcc-trunk/gcc/gcc.c:3423: error: passing argument 2 of 'execvp' from
incompatible pointer type
c:/MinGW/include/process.h:120: note: expected 'const char * const*' but
argument is of type 'char **'
This same error happens at stage 2 and 3. Working around it by compiling gcc.c
(and only gcc.c) without -Werror, I can confirm that the rest of the bootstrap
then goes fine.
