Specifies the file name for a precompiled header file.

This pragma is compatible with the following platform targets:

68K

PowerPC

NEC V800

Intel x86

MIPS

Embedded 68K

This pragma specifies the filename for a precompiled header file. If you don't specify the filename, the compiler gives the precompiled header file the same name as its source file.

Filename can be a simple filename or an absolute pathname. If filename is a simple filename, the compiler saves the file in the same folder as the source file. If filename is a path name, the compiler saves the file in the specified folder.

Listing 8.12 shows sample source code from the MacHeaders precompiled header source file. By using the predefined symbols __cplusplus and powerc and the pragma precompile_target, the compiler can use the same source code to create different precompiled header files for C and C++, 680x0 and PowerPC.
