2019-11-25Cleanup: move overflow safe alloc code into libsquashfsDavid Oberhollenzer
There were only a hand full of instances outside libsquashfs that used the alloc code. In most cases, the thing allocated hat its size derived from something already in memory anyway, so it is safe to assume its size fits into a size_t. At the same time, the opencoded Windows path conversion functions are all unified into a single helper function. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>

2019-11-23Fix various data type problemsDavid Oberhollenzer
- Make sure the mockup constant for AT_FDCWD is actualy an int - Don't use %lld printf format specified, mscrt doesn't have that - On 64 bit windows, use %I64u format specified for size_t - Seperate the overflow macro stuff from the form specifier stuff - Move the whole thing to compat.h and clean it up a little so it becomes readable.

2019-11-15Add missing "sys/sysmacros.h" header for back in for LinuxDavid Oberhollenzer
On BSD based systems, major(3), minor(3) and makedev(3) are defined in "sys/types.h", but on GNU/Linux systems they are in "sys/sysmacros.h", which is not available on the BSD systems. This patch fixes up compat.h to include "sys/sysmacros.h" on Linux based systems. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2019-11-15Fix build on BSD systemsAlyssa Ross
I tested FreeBSD, DragonflyBSD, NetBSD and OpenBSD and the endian macros weren't necessary (and in fact caused errors) on all of them. Because OpenBSD ships with an ancient GCC that doesn't support the checked addition/multiplication builtins, the build there would fail unless built with CC=cc or CC=clang. I changed configure.ac to prefer cc over gcc, so that the distribution's compiler preference is respected. (The default is [gcc cc]). I had to move AC_PROG_CC above LT_INIT because otherwise LT_INIT would run AC_PROG_CC first, and we wouldn't have a chance to use non-default parameters.
2019-10-28Add macro for printf format specifier for size_tDavid Oberhollenzer
The MSVC runtime is a wierdo C89 platform with some cherry picked features from C99 (which does not include the "%zu" format specifier). This commit adds a macro with a size dependend format specifier to be used instead. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
