compiler warning

I am seeing the following compiler warning for the past few days:

	basebackup.c:213: warning: variable `ptr' might be clobbered by
	`longjmp' or `vfork'

and I see this comment in the file:

	/*
	 * Actually do a base backup for the specified tablespaces.
	 *
	 * This is split out mainly to avoid complaints about "variable might be
	 * clobbered by longjmp" from stupider versions of gcc.
	 */

Seems that isn't working as expected.  I am using:

	gcc version 2.95.3 20010315 (release)

with -O1.
