 * plain CMake project globbing packages/core/*\/include
 * alphabetically): whether <sys/socket.h> resolves to lwip's own real
 * one (which reaches lwip/err.h) or libcglue's minimal one (which
 * doesn't) depends on include-path search order, which such a
 * consumer has no control over - found for real fixing ps2_drivers,
 * whose own ps2_eeip_driver.c hit "unknown type name 'err_t'" here.
 * Included directly instead - unambiguous regardless of resolution
 * order, since this package's own include_dirs always exposes
 * lwip_include (see package.yaml). */

 * #include <ps2ip.h> could actually see them (found for real:
 * nettest's DHCP bring-up, unbuildable without this).
 *
 * t_ip_info itself is NOT redefined here - libcglue's ps2sdkapi.h
 * already defines the one real, canonical t_ip_info behind a
 * T_IP_INFO_DEFINED guard for exactly this "more than one header wants
 * to supply it" situation (see its own comment). Guarding this copy
 * the same way means whichever header a consumer reaches first wins,
 * instead of a hard redefinition conflict - found for real rebuilding
 * this package after first pasting an unconditional copy here, which
 * broke ps2ip's own ps2ip_ps2sdk.c (reaches ps2sdkapi.h's copy first). */
