[fpc-pascal] FileExists inconsistency

[Jason P Sage]

I've written stuff in freepascal that can load and parse a directory and
decipher if it’s a directory or a file - even on POSIX (linux - Fedora 5).

I'm not saying this is a big achievement - but perhaps - at an expense of
speed - but in definitive returned results - I wonder if it would be prudent
to add a filexists routine or make the current one - do this type of
"thorugh checks".

I am aware of running to issue though with permissions - but these usually
make sense. If the file doesn't exist - but does - you don't have write
permissions.

I made a routine that goes through a couple steps - (probably the wrong way
but is portable) to both READ ONLY and READ WRITE (no actual writing) the
file just to see if I have read access and alternatively read/write.

This is great because if I need to verify a configuration file exists - I do
not necessarily need write permission ... and sometimes you do. Having a
little more info allows one to make more detailed error log files - and user
interface "messages" so users and administrators - heck - us
heads-down-coders can figure out what and why quickly when something doesn't
go as planned.
