ghc passing -undef to preprocessor and thereby eliminating OS specific defines
Hey, I am trying to adapt some code in the libraries when compiling for android (i.E. because some things are different on android to other posix systems). So in C code I would just do #ifdef __ANDROID__. While in the *.h and *.c files it seems to work, it does not work in *.hs files. I noted that the preprocessor is run like this: arm-linux-androideabi-gcc -E -undef -traditional -fno-stack-protector -DTABLES_NEXT_TO_CODE The -undef parameter is causing the __ANDROID__ define to be removed. Does it make sense to pass -undef to the preprocessor? Any other Ideas how I could adapt the code for android? Thanks!

You want to use: #ifdef android_HOST_OS the *_HOST_OS symbol is defined by GHC when it ivokes CPP.
