Hi, I'm looking for a way to set a GHC compile option on a specific module (not every module in the program) but only for a specific version of GHC. Ideally within the confines of cabal, and in a portable way. GHC provides the OPTIONS_GHC pragma, but it does not appear to provide a way for the pragma to fire for specific versions of GHC. Also, I can't use an #ifdef trick because "File-header pragmas are read once only, before pre-processing the file (e.g. with cpp)." Cabal provides conditional statements and a way to check the version of GHC, but I can't see a way to get it to only use certain compiler options for a particular module. In summary, what I really want is a modified version of the OPTIONS_GHC pragma: {-# OPTIONS_GHC ==6.12.1 ... #-} or a way to tell cabal to use certain compiler options for a particular module under certain conditions. Cheers, Bernie.
