section '.reloc' fixups data discardable ; readable

Seems I found a severe bug in DPMILD32: it deadlocks when a reloc section in not "readable" Above very-high-quality code should trigger a "missing import" complaint, instead, it deadlocks itself at black screen with white rat arrow - reacting to mouse movements, but not to CTL-C, CTL-BEAK, APPZ/CRASH/MENU, ... -> reboot unavoidable Uncommenting the "readable" or deleting complete section makes the bug vanish. Windaube, OTOH, seems to consider the section (all sections ?) unconditionally as readable.

IMHO the "readable" flag is crap - what's the point of a non-readable section ? Just ignore it and assume all readable

BTW, any plans to delete NE support from DPMILD32 ? Docs already flag it as "obsolete" , "no advantages" ... etc. - the time has come to kick it out
