[comp.windows.x] "compiler error: mismatched type" on Sun 4

brock@brock.cs.unc.edu (J. Dean Brock) (01/19/90)

While compiling the file mit/server/dix/events.c for a Sun 4
(running SunOS 4.0.3), I get the following error:

cc -c -O   -I../../. -I. -I../include -I../.././X11  -DXDMCP  -DSHAPE -DMITSHM -DMULTIBUFFER -DMITMISC -DINCLUDE_ALLOCA_H    events.c
"events.c", line 1793: compiler error: mismatched type on ?=

*** Error code 1

However, the file compiles ok if the -O option is omitted.
Anyone else have this problem?
