[CVS 2003-11-06]
Using `AC_CHECK_SIZEOF(int)' produces the following warning with -Wall
(output lines shortened):
configure.ac:78: warning:
AC_RUN_IFELSE called without default to allow cross compiling
general.m4:2281: AC_RUN_IFELSE is expanded from...
general.m4:1799: AC_CACHE_VAL is expanded from...
general.m4:1808: AC_CACHE_CHECK is expanded from...
types.m4:405: AC_CHECK_SIZEOF is expanded from...
configure.ac:78: the top level
but the documentation explicitly says that it `works now even when
cross-compiling'. Since this AC_RUN_IFELSE is deeply buried within
autoconf itself I suggest to suppress the warning message since it is
misleading otherwise.

PS: From a grammatical point of view, shouldn't it be rather `even
*if* cross-compiling'?)
