Summary:
The #define statement in Microsoft C versions 5.0, 5.1, 6.0, 6.0a, and
6.0ax accepts identifiers up to 31 characters. The compiler truncates
identifiers over 31 characters, and on warning level 1 or greater,
produces the following warning message:
warning C4011: identifier truncated to '<truncated identifier>'
This can cause potential problems if two or more identifiers are
identical up to the 31st character. If this is the case, the following
warning message appears for each additional #define that is identical
when truncated (on warning levels 1 or greater):
warning C4005: '<truncated identifier>' : redefinition
All of these identifiers are assigned the value of the last identifier
that was identical when truncated.
This information also applies to QuickC.
