!dec$ define works differently in debug and release

[LeonardB]

The enclosed sample code works differently when compiling for Debug and Release.

!dec$ define X first in the source code file is walid for the rest of the file when the setting is Release. 

When compiling for Debug is X defined only in first routine in the file

Interesting. Out of curiosity, turn off all IPO (both compiler and linker) and see what happens.

Isn't that interesting ... it's the -warn:interfaces switch.

You can work around this by expliciitly adding -DX on the command line.
