To select a different compiler, set the CC environment variable prior
to running configure e.g.

	CC=gcc-2.95 ./configure ...

Similarly for CFLAGS and LDFLAGS, e.g.

	CFLAGS='-g -Wall' ./configure ...

You can also override make variables with e.g.

	make CC=gcc-2.95

However, if you do this, bear in mind that the settings in head.<arch>
and config.h may not be appropriate.

Most distributions strip the dynamic libraries; sometimes the -devel
package includes static libraries which aren't stripped, but mostly
you have to build your own libraries if you want debug info.

In any case, I don't think that a debugger will help with the hanging
"exec" problem.
