From: Claudio Fontana <claudio.font...@huawei.com> This is the latest iteration of the memory search patch, including a trivial replacement for the memmem function for systems which don't provide one (notably Windows).
It detects the presence of memmem in configure and sets CONFIG_MEMMEM, providing a trivial implementation for the !CONFIG_MEMMEM case. The new code is MIT licensed, following usage of other files in the same directory dealing with replacement functions (osdep, oslib, getauxval etc), and to maximize reusability. I have tested this in both CONFIG_MEMMEM defined/undefined scenarios, but more feedback and testing is welcome of course. changes from v5: dropped the import from gnulib and implemented a trivial replacement. changes from v4: made into a series of two patches. Introduced a memmem replacement function (import from gnulib) and detection code in configure. changes from v3: initialize pointer variable to NULL to finally get rid of spurious warning changes from v2: move code to try to address spurious warning changes from v1: make checkpatch happy by adding braces here and there.
