Summary: liblicense.0.4 - gcc -ansi

Initial Comment:
This change set increases the portability of the C code - to compilers other
than GCC - by avoiding post-1989 features of the C language definition. Yes:
18 years later and they STILL haven't caught up.

I haven't committed this to my repo yet, I'd like to know what folks think.

Personally, I'd rather be coding in C++, where mixed declarations and
statements are OK. They make a lot of sense. Problem is that most compilers
except GCC are, well, behind the times.

The no-c++ comments thing is important programmer psychology. It provides
the reader with an almost subliminal clue that they are dealing with C, and
not anything else.

Attached is a new improved patch. It gets rid of alloca, and it fixes the
flat_file.c problem.
File Added: liblicense.0.4.c24.patch.txt

sf.net has it still assigned to you, scott.
please commit the patch, if you agree that I can fix the alloca in another
change set (soon!)

I see a bug in flat_file.c. If fgets() doesn't read anything, tmp should
explicitly be set to NULL (or is it the empty string (Scott?)). Otherwise,
tmp remains uninitialized and we return jibberish. The file will be empty
when the default license has been unset.

Getting rid of c++ comments is a clear OK. Getting rid of mixed
declarations and statements couldn't hurt (although I agree, it's lame and
annoying that there are still compilers out there that haven't gotten their
act together).

I'm unsure of using alloca(). I'm not all that familiar with it, but it
sounds like it's discouraged and has many buggy implementations. I'd
prefer to use malloc() instead. ll_new_license_chooser is typically only
called once during the entire session, so we're not looking at a
significant performance hit allocating on the heap verses the stack.

Looks good. Compiler portability is not something I've dealt with so I'll
take your word for it. Shall I commit it?
