I use the following:

• char: "char", as in "charbroiled". It rhymes nicely with "star", so "char *" comes off as "char star".
• !: Intriguing; I'm not sure I've ever pronounced this aloud. I'd probably say "exclamation point", to be honest, just to be clear.
• #: "Hash", although sometimes in my head I also say "number".
• *: "Star"
• Regex: "REG-ex". It's interesting, since "regular" has a hard g, but I suppose the soft g flows better.
• SQL: Maybe I differ from most people, but I say "sequel", except in the case of PostgreSQL. I've heard you can tell on what RDBMS programmers cut their teeth, as those who learned on SQL Server tend to say "sequel" and everyone else tends to say "ess cyoo ell". Not sure if that's true, but it's true in my case. :)
• |: "Pipe". Duh. :)
• bin: "bin" rhymes with "pin"
• lib: "lib" as in "liberate"
• etc: "ets-see", as in "slash ets-see". :)
• /: "Slash". It annoys me when people call it a backslash, too -- so much that I wrote a blog post about it many moons ago.
• LaTeX: I say "LUH-tech".

I'll throw another one in the mix:

• Mac OS X: It's "Mac OS Ten", not "Mac OS Ex" :)
