[Tinycc-devel] [PATCH] preprocess all files from a command line with a -E switch

[Sergey Korshunoff]

Don't drop a preprocessor defines when tcc going to preprocess a next
file in the same pass like
        tcc -E one.c two.c three.c -o combined.i

Currently tcc don't handle such case. The new behavior is better then
the current one. After a patch it is possible to compile combined.i
in case:

* include files are properly protected by
        #ifndef MY_INCLUDE_H
        #define MY_INCLUDE_H
          extern void func();
        #endif
* there is no incompatible declarations for the same name in *.c

An archive for a test purpose is included
