UWIN - Overriding /Od with /Ox warning message?
The following warning may appear on UWIN:
$ nmake + cc -O -D_BLD_DLL -g -I- -D_TRACE_ -c foo.c Command line warning D4025 : overriding '/Od' with '/Ox'
The UWIN cc wrapper translates -O to the cl.exe option
-Ox which is max optimizations. The wrapper also converts
-g to -Zi -Od. -Zi generates
debug information and -Od disables optimizations.
When CCFLAGS+=-g is used, -g is appended to the
default CCFLAGS which gives us -O -g. The
UWIN cc wrapper then passes -Zi -Od -Ox to cl.exe, which
gives the warning message since the two optimizer flags conflict.
If the default -O flag is removed from CCFLAGS
by setting CCFLAGS=-g, then -Ox is not passed
to cl.exe and no warning is generated.
