Hum, OK. This should probably have been explained in the commit log
and/or in a comment above the workaround. But if indeed
-mcompact-eh/-mno-compact-eh are available only in the Mentor
toolchain, then your proposal is the most appropriate one.

Or, alternatively, we could simply add this as a forced CFLAGS when
this toolchain is used, which would also avoid the need for a similar
workaround in the libffi package.

Best regards,

Thomas
