# 32-bit Linux build.
#   * g++ 13 rather than clang++-devel: it is what the port is validated on
#     and it supports -std=c++23 (needed by the existing CFLAGS).
#   * The 32-bit dependency set lives in /opt/m2port/extern/Linux40250; the
#     FreeBSD absolute paths (/usr/local/lib/mysql, /usr/lib/libssl.a, ...)
#     have no Linux equivalent and would silently pick up 64-bit host copies.
#   * M2_EXTERN_LINUX can be overridden from the command line.
#   * -DBOOST_BIND_GLOBAL_PLACEHOLDERS silences boost/bind.hpp's global
#     placeholder deprecation #pragma message (main.cpp includes it).
#   * NOT defined, deliberately: _TIME_BITS=64.  sizeof(time_t) must stay 4
#     under -m32 - see the static_asserts in packet.h.  -D_FILE_OFFSET_BITS=64
#     alone would be safe but nothing here needs it, so it is left off too.
