New sed or awk question,thanks for last answer

[rkc]

Thanks to those who answered my last sed question concerning stripping blank
lines and lines starting with # from a file. The solution was:
	sed  -e '/^#/D' -e '/^[<space><tab>]*$/D' filename    or
	sed  -e '/^#/D' -e '/^[<space><tab>]*$$/D' filename   in a makefiley

My new question is much tougher, (I'm not certain it can be done with sed, or
grep, but that it may require awk.)  I want to strip out all of the subroutine
definitions of a file up to and including the { character.  In other words,
give a file with
/*
	Lots of comments
*/
float *
	function_name(arg1,arg2)
argtype arg1;
argtype arg2;
{
	<the fn>
}
I want to get back:
float *
	function_name(arg1,arg2)
argtype arg1;
argtype arg2;
{

Does anyone have code that does this, or can anyone suggest a script to do
this?  Thanks for your help.
