Please describe the problem:
Because of C99ism in the file glib/gmem.c, glib does not compile.

Steps to reproduce:
1. compile by old compiler

Actual results:
following messages are displayed. (Visual C++ 6.0)

Expected results:
The declaration have to be moved to top of block.

Does this happen every time?
