I don't expect this to actually come up in any circumstance, but it prevents a warning in some versions of gcc that would otherwise arise from the use of 'int' to compute the input size: if gcc isn't confident that the int is positive, then it complains that possible inputs to malloc might be in the region of 2^64 - (small multiple of a negative 32-bit int). I would hope malloc would fail in any case on such an input, so failing a couple of lines earlier makes no important difference. Annoyingly, stdint.h is missing in my NestedVM build setup (though it has stdbool.h - it's not _totally_ C90). So I have to check that at cmake time. Also, removed the #defines for smalloc and friends from the tree234 test mode. These were needed in the old build system, when tree234-test was built ad-hoc without being linked against malloc.c. But now tree234-test links against the same utils library as everything else, and can use the real smalloc - and doing so prevents another of these warnings when compiling with -flto.
This is the README accompanying the source code to Simon Tatham's puzzle collection. The collection's web site is at <https://www.chiark.greenend.org.uk/~sgtatham/puzzles/>. The puzzle collection is built using CMake <https://cmake.org/>. To compile in the simplest way (on any of Linux, Windows or Mac), run these commands in the source directory: cmake . cmake --build . The manual is provided in Windows Help format for the Windows build; in text format for anyone who needs it; and in HTML for the Mac OS X application and for the web site. It is generated from a Halibut source file (puzzles.but), which is the preferred form for modification. To generate the manual in other formats, rebuild it, or learn about Halibut, visit the Halibut website at <https://www.chiark.greenend.org.uk/~sgtatham/halibut/>.
