dnl Top-level configure.in for wxWindows by Robert Roebling, Phil Blecker,

dnl initialization
dnl ---------------------------------------------------------------------------

dnl the file passed to AC_INIT should be specific to our package
AC_INIT([wx-config.in])

dnl sets build, host, target variables and the same with _alias
AC_CANONICAL_SYSTEM

dnl When making releases do:
dnl
dnl WX_RELEASE_NUMBER += 1
dnl
dnl ..and update WX_CURRENT, WX_RELEASE and WX_AGE according to the
dnl following rules:
dnl
dnl    If any changes have been made to the public interface, that is if any
dnl    exported class, method, global or global type has been added, removed
dnl    or changed in any way, then do:  WX_CURRENT += 1
dnl
dnl    If source changes have been made that *do not* alter the public
dnl    interface then do:  WX_REVISION += 1
dnl    If WX_CURRENT was incremented (as above) instead do:  WX_REVISION = 0
dnl
dnl    If any public interface was added, do:  WX_AGE += 1
dnl    If any public interface was removed (or altered in a way effectively
dnl    removing the previous definition), instead do:  WX_AGE = 0
dnl
dnl When the major or minor version numbers are incremented, all the above
dnl variables should be reset to 0.
dnl
dnl The resulting library name will be of the form:
dnl   libwx_$(TOOLKIT)-$(WX_RELEASE).so.$(WX_CURRENT).$(WX_REVISION).$(WX_AGE)

dnl do it manually. We can't use AC_TRY_COMPILE(), either, because it doesn't
dnl check if the symbol is available at linking time

dnl we use AC_TRY_LINK() here instead of AC_TRY_RUN() to make the checks
dnl work for cross-compilation, but AC_TRY_LINK() normally only compiles
dnl one function while we need at least 2 - hence the ugly hack below. To
