Description
Running wsdiff between two proto areas built from the same workspace, I kept
seeing the amd64 libast's .rodata change. In an attempt to verify that wasn't
my doing, I built an unchanged workspace, twice, and compared the two.
The amd64 libast and libshell still differed in their .rodata:
usr/lib/amd64/libast.so.1
NOTE: ELF .rodata difference detected.

I can find no explanation of this, and do not see changes in the i86 libast or
libshell.
Asking around, carlsonj commented that it looked like the static data for
_ast_strtold or tokscan, but was unclear beyond there.
Frequency
Often
Regression
No
Steps to Reproduce
Build the same workspace twice (saving the first proto area off to the
side), then wsdiff the two resulting proto areas. (mine were DEBUG)
Expected Result
No changes in resulting objects.
Actual Result
often libast, and slightly less often libshell differ between consecutive,
unchanged, builds of the same workspace

Can you please test whether the problem still occurs with B97 (e.g. after the
SCCS--->Mercurial/hg transition (which made the SCCS tag stuff obsolete)) ?
