Bug#26294: library name conflict between MySQL 4.x, 5.0 and Qt 3.3

cmiller@zippy.cornsilk.net · cmiller@zippy.cornsilk.net · commit 9ff7a0cedca7 · 2008-04-03T11:32:00.000-04:00
When linking with some external programs, "multiple definition 
of `init_time'"

Rename init_time() to my_init_time() to avoid collision with other
libraries (particularly libmng).
