Compilation fails on TCC#97

Compilation fails on TinyC (TCC) because of a C99 feature it apparently doesn't support: ``` tcc -I./src -Wall -Wextra -Werror -std=c99 -O0 -g -c -I./tests -o tests/main.o tests/main.c In file included from tests/main.c:3: tests/munit/munit.h:401: error: 'size' undeclared make: *** [Makefile:124: tests/main.o] Error 1 ``` The troublesome line: ```c void munit_rand_memory(size_t size, munit_uint8_t buffer[MUNIT_ARRAY_PARAM(size)]); ``` This is the macro definition: ```c #if defined(__STDC_VERSION__) && (__STDC_VERSION__ >= 199901L) && !defined(__PGI) # define MUNIT_ARRAY_PARAM(name) name #else # define MUNIT_ARRAY_PARAM(name) #endif ``` If we ensure `__TINYC__` is undefined, it compiles. ```c #if defined(__STDC_VERSION__) && (__STDC_VERSION__ >= 199901L) && !defined(__PGI) && !defined(__TINYC__) // ^^^^^^^^^^^^^^^^^^^^^^ ```
