For the sake of completeness, they are a few months I use this patch:

Bootstrapping on Cygwin needs about 24 MB for STATIC_HEAP_SIZE, after 
the first build of binaries; it needs 'only' about < 19MB, after the 
final build of binaries.


So, if I want a full bootstrap, I configure with:

-DBOOT_STRAP  ${source_dir}/configure...

If I bootstrap on GNU/Linux, make-dist --snapshot... then I can build 
(NO bootstrap) configuring

  ${source_dir}/configure


Any other solution (mainly reducing STATIC_HEAP_SIZE) is good.


Cheers,
    Angelo.
