On Fedora 17, 'gmake bootstrap' does delete src/epaths.h
as part of the 'bootstrap-clean' action, but it goes on
to recreate it as part of './config.status --recheck' or
'./configure'.  Can you investigate why the latter doesn't
occur for you?  Perhaps append '&& find . -name epaths.h'
to the MAKE_CONFIG_STATUS macro definition.

That's an unwanted clash between <string.h> and Emac's stdalign.h
substitute.  Should be harmless.  I'll look into fixing that by
prepending "#undef _Alignof" to the stdalign.h substitute.
