That still looks fishy.  Those should be symlinks, and ls should show
them as such, not as .lnk files.  Out of curiosity, from a CMD prompt in
that dir what does "attrib cc1.exe.lnk" say?  Does it have the R bit
set?  I checked your cygcheck and it appears that you have Cygwin
installed on C: which is NTFS, so FAT shouldn't be an issue.  You don't
happen to have anything set in the CYGWIN environment variable that
would affect symlinks?  What happens if you manually run the preremove
and postinstall scripts from a bash prompt, i.e. ".
/etc/preremove/gcc-mingw-core.sh; .
/etc/postinstall/gcc-mingw-core.sh.done".  That should remove and then
recreate those files.  Do you have working symlinks then?

That's not really a useful debugging method.  Running any Cygwin binary
without /bin in the path is going to give an error about a missing DLL. 
And cc1 is not meant to be invoked directly so it won't print anything
useful.
