MPC 1.4.1.bcr.1

Bazel port of GNU MPC using rules_cc_autoconf for platform-specific configuration.

Patches

remove_pregenerated_headers.patch

The upstream tarball ships pre-generated src/mpc.h and src/mpc-impl.h (produced by ./configure on the release machine) alongside the .in templates. These pre-generated copies hardcode MPC_HAVE_COMPLEX_H=1, which is incorrect on Windows/MSVC where complex arithmetic operators are unsupported. They also conflict with the autoconf_hdr-generated versions under Bazel's strict include sandboxing.

This patch deletes both files so that only the autoconf_hdr-generated versions (from the .in templates) exist, with the correct MPC_HAVE_COMPLEX_H value per platform.

bazel_test_srcdir.patch

MPC's test framework locates .dat and .dsc data files via getenv("srcdir"). Under Bazel, test data files live in the runfiles tree at paths that vary across Bazel versions and platforms. This patch adds a MPC_BAZEL_TEST-guarded code path to open_datafile.c and read_data.c that uses the rules_cc C++ runfiles library (via bazel/runfiles_util.h) to resolve data file paths from the MPC_SRCDIR environment variable.
