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 2.1.1 for the first one, HP-UX for the second) it's available in the

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
dnl understand why it works, remember that AC_TRY_LINK() just prepends
dnl "int main() {" in the beginning of the code and "; return 0; }" at the

dnl if we fail to find vsnprintf, also try for _vsnprintf as that is what

dnl final note: AC_TRY_LINK will only be executed if there is nothing in
dnl the cache so we have to do AC_DEFINE(HAVE_VSNPRINTF) below and not inside
