At what warning and compliance level?
With the default warning level, some of the failures are silent, but can
cause incorrect code to be generated.
In particular, malloc() will be substituted for the built in alloca()
macro, unless Tru64 has the alloca.h header file.
Of course that could also be dependent on the configure tests for the
alloca() function being fixed. I will only see the ones that make it into
the config.h.in file.
In some cases at the default warning level, warnings are suppressed
because the compiler assumes it knows what was really intended, even
though the actual code is ambiguous or in violation of the current
A cross platform product with multiple maintainers generally needs to have
as high a warning level set as can be practically maintained.
With the "questcode" warning level enabled, the Compaq C Compiler even
flags legal code that has a high probability of being in error.
