Hi,
I only just joined this list so please excuse aberrant behaviour.
I am also in the same situation as Matt, but I have more
information about it.
First, you can easily work around it by telling devstudio to
invoke flex through bash:
c:\cygwin\bin\bash -c flex ...
This is with 2.5.31-1, my previous version was 2.5.4-2.
Previous experience with DevStudio has suggested to me that it
invokes external commands via command.com, so I checked invoking flex
manually with identical arguments under bash and under command.com. The
result is that it always seems to work under bash, but under command.com it
can give a command-line summary, but not compile my script (I only have the
one script handy to test it under). So I think the problem is invocation
under command.com, not anything about DevStudio per se.
I'm attaching a cygcheck output.
I'm not sure whether flex should invoke under command.com? e.g.
is there a difference between invoking an isolated cygwin executable by its
full path, and invoking one which tries to access other executables, and
which may not have a PATH set up?
In any case, I have a simple work-around, so this is JFYI.

I want to use flex in Visual Studio, but it won't run. It just says:
flex: fatal internal error, exec failed
It worked before I upgraded Cygwin a few days ago. I don't know what
version of flex I was using before, but this happens with version 2.5.31.
Thanks!
