[PATCH, committed]: Zone collector

[Kelley Cook]

Daniel,

Attempting to bootstrap on i686-pc-cygwin with --with-gc=zone, I get

$ gcc -c --save-temps  -g  -DIN_GCC   -W -Wall -Wwrite-strings 
-Wstrict-prototypes -Wmissing-prototypes -pedantic -Wno-long-long 
-DHAVE_CONFIG_H    -I. -I. -I../../gcc-snapshot/gcc 
-I../../gcc-snapshot/gcc/. -I../../gcc-snapshot/gcc/../include 
../../gcc-snapshot/gcc/ggc-zone.c -o ggc-zone.o
../../gcc-snapshot/gcc/ggc-zone.c: In function `alloc_small_page':
../../gcc-snapshot/gcc/ggc-zone.c:626: error: `entry_size' undeclared 
(first use in this function)
../../gcc-snapshot/gcc/ggc-zone.c:626: error: (Each undeclared 
identifier is reported only once
../../gcc-snapshot/gcc/ggc-zone.c:626: error: for each function it 
appears in.)
../../gcc-snapshot/gcc/ggc-zone.c:664: error: structure has no member 
named `page_groups'
../../gcc-snapshot/gcc/ggc-zone.c:669: error: structure has no member 
named `bytes_mapped'
../../gcc-snapshot/gcc/ggc-zone.c:674: error: structure has no member 
named `free_pages'

Grepping for entry_size, shows that it is never declared within 
ggc-zone.c but it is within a highly similar block in ggc-page.c.

Likewise for the structure G which in ggc-zone.c doesn't have 
page_groups, bytes_mapped, nor free_pages as members, but they are 
present in ggc-page.c

Copy and paste errors?
