Current CVS bootstrap failure on i686-pc-linux-gnu

[Gabriel Dos Reis <gdr at codesourcery dot com>]

I think the patch 

    2000-05-27  Geoffrey Keating  <geoffk@cygnus.com>

is causing the bootstrap failure I seeing on an i686-pc-linux-gnu.
The bootstrap fails with the following message:

[...]

/home/gaby/egcs/gcc/regclass.c: In function `record_operand_costs':
/home/gaby/egcs/gcc/regclass.c:864: `reg_changes_size' undeclared (first use in this function)
/home/gaby/egcs/gcc/regclass.c:864: (Each undeclared identifier is reported only once
/home/gaby/egcs/gcc/regclass.c:864: for each function it appears in.)

[...]

make[2]: *** [regclass.o] Error 1
make[2]: Leaving directory `/tmp/E/gcc'
make[1]: *** [bootstrap] Error 2

Indeed the variable reg_changes_size is conditionally defined as:

   #ifdef CLASS_CANNOT_CHANGE_SIZE

   /* These are the classes containing only registers that can be used in
      a SUBREG expression that changes the size of the register.  */

   static int class_can_change_size[N_REG_CLASSES];

   /* Registers, including pseudos, which change size.  */

   static regset reg_changes_size;

   #endif /* CLASS_CANNOT_CHANGE_SIZE */

But it is used unconditionally.
