Hello again Sven/Thomas,

     Sorry about the post again, you can ignore the previous post. I got 
targetandroid compiling with my buildscript.
I just had to do a make -C "$HOME/fpc-droid/utils/fpcm" before the 
actual make process, and setting PATH to 
"$HOME/fpc-droid/utils/fpcm:$PATH" as a workaround.

     I'm sure when it is merged you won't have to worry about the 
fpcmake as it will be aware of arm-android.  I thank you very very much 
for starting this branch.  I just wish I would've stumbled upon it 
sooner rather than doing it myself based on arm-linux.  A quick demo 
works now with Android's NativeActivity.  I imported Google's 
'libandroid_native_app_glue.a' and the headers from the 
lcl/interfaces/customdrawn/android interface from Lazarus with success.  
I only had to change the 'ANativeActivity_onCreate' translation.  Now if 
only you could include NativeAppGlue (record's and procedure interfaces) 
and the other header translations from 
lcl/interfaces/customdrawn/android that would be most excellent. :)

Thank you very much again for saving me a lot of time.

- Dennis
