From cfe9f4d6b0a5d10a15e10e987d528c5c513a42f1 Mon Sep 17 00:00:00 2001 From: Florian Weimer Date: Tue, 19 Dec 2023 11:00:11 +0100 Subject: [PATCH] configure: Only text the makecontext signature we need The test/explicit-bzero.c test uses a start routine without any arguments. There is no need for the multi-argument version. This avoids a build failure with glibc and future compilers. The GNU C library declares the makecontext callback of type void (*) (void), so no cast is needed. On other systems, the type may be the (currently distinct) type void (*) (), but given that this only affects the ability to execute a test, no further machinery is added here to detect that different type.
