[FIX] Build fails on GCC 13.2.1 with `dex_instruction.c:655:43: error: argument 2 of type ‘u4[kMaxVarArgRegs]’ {aka ‘unsigned int[kMaxVarArgRegs]’} declared as a variable length array [-Werror=vla-parameter]`

I am building with GCC version 13.2.1.

./make.sh fails with

[...]
gcc -c -std=c11 -D_GNU_SOURCE -Wall -Wextra -Werror -DVERSION=\"dev-78f283b\" -c dex_instruction.c -o dex_instruction.o

cc1: all warnings being treated as errors
make: *** [Makefile:56: dex_instruction.o] Error 1

A manual workaround is to issue make CFLAGS="${CFLAGS} -Wno-error=vla-parameter" -C src instead of ./make.sh.

i found that you can edit src/Makefile and remove '-Werror' to build it

Ahoj,

now that a fix is known, how about implementing the fix, @anestisb?

I have created a pull request.
You can try Fixed version and build it.
Maybe later i'll create a release.

You can try [Fixed version](https://github.com/RJMultiDev/vdexExtractor) and build it.

I am fine with manual `make` invokation specifiying manually the needed `-Wno-error`-statement as I already mentioned in my reporting post.
