34.2. Source Pre-Processing

C sources are pre-processed with the following tools before being passed to the C compiler:

utils/comment5.c

Convert /bin/sh-style comments (lines starting with "# ") to C-style comments (/**/).

Warning

The use of /bin/sh-style comments is deprecated.

utils/varbrace.d
Add braces to C source code, so that variable declarations (introduced with the pseudo-keyword var) can be used within blocks, like in C++ and C99.
utils/ccpaux.c
When cpp cannot handle indented directives, remove the indentation.
utils/gctrigger.d
Add GCTRIGGER statements at the head of function bodies (for functions marked with the maygc pseudo-keyword).
utils/deema.c
When cpp cannot handle empty macro arguments, insert _EMA_ instead.
utils/ccmp2c.c
For the clx/new-clx module only. Allows cpp-style preprocessing before modprep processing. Should be merged into modprep eventually.
utils/modprep.lisp
For some modules only, see Section 32.2.7.1, “Modprep”.
utils/unicode/

Generate NLS files in src/.

utils/unicode/UnicodeDataFull.txt
Character descriptions from Unicode 3.2; used by DESCRIBE and installed in data/ under CUSTOM:*LIB-DIRECTORY*.
