File names with +?

[Jose Emilio Labra Gayo]

I was trying to compile a file "h++.hs" and it seems that ghc does not
like that name. When I try to compile it, I obtain:

//h++\.hi/: nested *?+ in regexp at /usr/local/lib/ghc-4.08/ghc-iface.prl 
line 141.

If I rename the file as "hpp.hs" then it works fine.

Best regards, Jose Labra
