Not exactly. #pragma is #pragma and sometimes you just have to bite
the bullet and manually surround preprocessor
directives with platform #ifdefs
#ifndef __Z_OS__ /* or whatever is the platform tag for you */
#pragma(foo)
#endif
Will using this use of ifndef solve the issue that if a compiler
option is set at launch time due to being coded in the JCL or via a
DD it can/will override the pragma supplied setting? The issue that
was raised is that there is apparently no way to override the global
settings via a pragma in the source code of a module being compiled.
Unless this happens all the ifndef does is supply options to be used
when compiling under Z/OS SO LONG AS THE COMPILER does not override
the requested option due to a Global Default override.
