dnl check for vsscanf() and vsnprintf() - on some platforms (Linux, glibc
dnl 2.1.1 for the first one, HP-UX for the second) it's available in the
dnl library but the prototype is missing, so we can't use AC_CHECK_FUNCS here,
dnl do it manually

dnl we use AC_TRY_COMPILE() here instead of AC_TRY_RUN() to make the checks
dnl work for cross-compilation, but AC_TRY_COMPILE() 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_COMPILE() just prepends
dnl "int main() {" in the beginning of the code and "; return 0; }" at the
dnl end...

dnl if we fail to find vsnprintf, also try for _vsnprintf as that is what
dnl we'll find under MSW if it exists.

dnl final note: AC_TRY_COMPILE 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
dnl it or the symbol wouldn't be defined for the 2nd and subsequent configure
