OCC Warning Control
/E\[+\]nn error control
nn is the maximum number of errors before the compile fails. By default only 25 errors will be shown and then the compiler will abort.
If + is specified extended warnings will be shown that are normally disabled by default; for example: OCC /E+44 myfile.c enables extended warnings and limits the number of errors to 44.
/wxxx warning control
The /w switch controls the warning output. Note that by default or as a result of the /E switch some warnings may be automatically disabled.
There are a variety of options.
