This is really a hack, because non-functional compiler options should not be exposed to callers as if they worked. --- m4/dpkg-compiler.m4 | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/m4/dpkg-compiler.m4 b/m4/dpkg-compiler.m4 index 4a88ab1d0..7c5ba8d19 100644 --- a/m4/dpkg-compiler.m4 +++ b/m4/dpkg-compiler.m4 @@ -28,7 +28,7 @@ AC_DEFUN([DPKG_CHECK_COMPILER_FLAG], [ AS_VAR_COPY([dpkg_varname_save], [dpkg_varname]) AS_VAR_SET([dpkg_varname], ["-Werror dpkg_check_flag"]) AC_COMPILE_IFELSE([ - AC_LANG_SOURCE([[]]) + AC_LANG_SOURCE([[int function() { return 0; }]]) ], [ AS_VAR_SET([dpkg_varname_cache], [yes]) ], [ -- Dpkg.Org's dpkg
