Somewhy it happened that in my trunk I have platform.h in
extern/icu/source/common/unicode. No idea how did it arrive in that dir
(certainly, not under version control). As far as I know about Android,
icu libraries are present in default device's setup. But question comes
- what is best way to access them when doing cross-build?

Ahh - thank you.

Using latest NDK one can build complete native application. But for
firebird this does not appear critical - first of all we provide
libraries, out utlities do not make much sense (except for people who
have non-standard Android with command line support). I hope that to
start daemon on linux we need not have Java wrapper for it? :-)

That's not completely true. Setting correct flags for linker one can use
at least exceptions without any problems. They should not cross module
boundaries - but that's OK for us.
