gcc HEAD fails to build.

gcc HEAD fails to build.

[George France]

Greetings,

gcc from the HEAD cvs tree snapshot that I took an hour ago is failing to 
build on i686-pc-linux-gnu, as follows: 

   Bootstrap comparison failure!
   c-parse.o differs
   objc-parse.o differs
   make[1]: *** [compare] Error 1
   make[1]: Leaving directory 

It built correctly from the cvs snapshot that I took 24 hours ago.  Any Ideas 
what has changed???

Thank you in advance.

Best Regards,


--George

	Are you sure that c-parse.in did not change between the phases?
That is exactly the files affected by Aldy's patch.  If not, you might try
reverting Aldy's patch because his report of libstdc++ build failure is
worrisome.

i've been noticing that too.  i thought c-parse.in did not affect c++.

in any case, i'm going to investigate.
