Sorry, I found this e-mail address on
http://freeware.sgi.com/fw-5.3/fw_GNUbison/GNUbison.html

I'm just submitting this problem I'm experiencing. If you don't make any
support please forget my request.

I'm using yacc tool to interpret a simple language. It was working very
fine until I bought a new computer (let's call it NEW and OLD the
previous). I re-installed the whole stuff and when I parse my xxx.y file
I get as usual the y.tab.c and y.tab.h but the content of these files is
corrupted. For instance in y.tab.h at some point I see part of the
content of y.tab.c.
Notice that the same .y parse correct on OLD but there is more ...
I also tried to share the disk from NEW and parse from OLD: it doesn't
work.
I try to summarize my investigation:

NEW
  DISK E:
      \cygwin\...
      \my project\xxx.Y   -> WRONG

  DISK H: -> \\OLD\D:
      \my project\xxx.Y   -> OK


OLD
  DISK D:
      \cygwin\...
      \my project\xxx.Y   -> OK

  DISK H: -> \\NEW\E: (H:\cygwin was also renamed !)
      \my project\xxx.Y   -> WRONG

it seems there is something related to the disk but I don't understand
what. Can you see where is the bug?
Any suggestion to help solving the problem is welcome.
Thanks in advance, Oscar Porta.
