+Subject: [PATCH] m4/ccforbuild.m4: include <stdlib.h> in test program
+
+The GMP_PROG_CC_FOR_BUILD_WORKS and GMP_PROG_EXEEXT_FOR_BUILD macros
+do various checks to verify if the host compiler works, but their test
+programs lack the inclusion of <stdlib.h>, needed for exit(). This
+causes a build failure with gcc 14.x:
+
+conftest.c: In function 'main':
+conftest.c:4:3: error: implicit declaration of function 'exit' [-Wimplicit-function-declaration]
+    4 |   exit(0);
+
+which then causes the configure script to think that the host compiler
+does not work:
+
+configure: error: Specified CC_FOR_BUILD doesn't seem to work
+
+so let's include <stdlib.h> to fix this issue.
