Thanks all!
/bin/bash -c "" seems to work; though I had tried in simple tests and were expecting that ps -aef | grep bash would show another bash. Guess it just executes and goes off.
To give the context, I was looking for this is that we have a make file which calls for autoconf ./configure along with some arguments for the configure script (in a single line). This by-default looks for the gcc compiler where as I want the configure script to take IBM's xlc compiler (my platform being an AIX machine). Somewhere, I came to know that the configure scripts would look for exported value of CC to decide on the compiler to be used in the makefile generated by it.
Hence, I needed to call bash before ./configure and set the environment var CC for the path of the xlc (on the same line); this was to me without luck and made me to look for your help.
Thanks, I'll try once again tomorrow morning and would update across.

libbash
LIBBASH(7) libbash Manual LIBBASH(7)
NAME
libbash -- A bash shared libraries package.
DESCRIPTION
libbash is a package that enables bash dynamic-like shared libraries. Actually its a tool for managing bash scripts whose functions you may
want to load and use in scripts of your own.
It contains a 'dynamic loader' for the shared libraries ( ldbash(1)), a configuration tool (ldbashconfig(8)), and some libraries.
Using ldbash(1) you are able to load loadable bash libraries, such as getopts(1) and hashstash(1). A bash shared library that can be loaded
using
ldbash(1) must answer 4 requirments:
1. It must be installed in $LIBBASH_PREFIX/lib/bash (default is /usr/lib/bash).
2. It must contain a line that begins with '#EXPORT='. That line will contain (after the '=') a list of functions that the library
exports. I.e. all the function that will be usable after loading that library will be listed in that line.
3. It must contain a line that begins with '#REQUIRE='. That line will contain (after the '=') a list of bash libraries that are
required for our library. I.e. every bash library that is in use in our bash library must be listed there.
4. The library must be listed (For more information, see ldbashconfig(8)).
Basic guidelines for writing library of your own:
1. Be aware, that your library will be actually sourced. So, basically, it should contain (i.e define) only functions.
2. Try to declare all variables intended for internal use as local.
3. Global variables and functions that are intended for internal use (i.e are not defined in '#EXPORT=') should begin with:
__<library_name>_
For example, internal function myfoosort of hashstash library should be named as
__hashstash_myfoosort
This helps to avoid conflicts in global name space when using libraries that come from different vendors.
4. See html manual for full version of this guide.
