Which exception handling mechanism is used by the DJGPP port?
Is it (GCC) SJLJ?
No. Updated to set ZCX_By_Default := true for DJGPP.
Well I'm confused now. How could this work before? In other words, has the
target runtime been tested/used by anyone?
GCC Ada compiler itself uses exceptions. I mentioned bootstrap failure of GCC recent trunk version
for traget libada. It causes an exception to be raised. That worked in last test build (r239639
with DJGPP related patches applied, last version of patches for Ada). I also got identical failure
with 20160831 trunk version where XCZ_By_Default was still false (my old patch set version that was
maintained for a long time)
Attached output is from last test build (r239639 with DJGPP related patches applied, last version
of patches for Ada).
