[boost] [tools/regression] Borland patch for compiler_status.cpp

From: Nicola Musatti (Nicola.Musatti_at_[hidden])
Date: 2006-02-28 17:23:30

Hallo,
the following patch makes it possible to compile compiler_status.cpp 
with the Borland compilers. Apparently under some conditions the Borland 
compiler issues an error for a valid use of the ternary operator. It is 
sufficient to wrap the whole expression in parentheses to overcome the 
problem. The same workaround is applied twice in the patch.

Cheers,
Nicola Musatti
