[Tinycc-devel] [patch] symbol allocator

[Marcelo Jimenez]

Simplifying/clarifying the symbol allocator:

sym_free_first *must* be NULL upon the entry of __sym_malloc, this is
the entry condition. Also sym_free_first will be imediately
overwritten upon return of __sym_malloc, so there is no need to set
it.
