Funny. The testcasewriting gcc wiki page at
http://gcc.gnu.org/wiki/TestCaseWriting
suggests a double pipe. Quoth the Raven:
Should a line produce two errors, the regular expression should
include an "||" (ie. a regular expression OR) between the possible
message fragments.
If a single pipe is indeed to be used, perhaps we want to correct that
piece of documentation, lest
fools follow its advice. :)
