MTEST.C

/* ------------------------------------------------------------------
 * MTEST.C - direct INT 33h probe, bypassing RATON.LIB completely.
 * Tests DOSBox's mouse emulation at the lowest level so we know
 * whether the problem is in DOSBox or in the RATON library.
 * Build:  set MAIN=MTEST.C  in BUILD.BAT, run BUILD, then run MTEST
 * (plain text mode - no iniciagra() needed)
