57 requires { CYGBLD_ISO_ERRNO_CODES_HEADER == "<cyg/error/codes.h>" }
59 This package contains the common list of error and
60 status codes. It is held centrally to allow
61 packages to interchange error codes and status
62 codes in a common way, rather than each package
63 having its own conventions for error/status
64 reporting. The error codes are modelled on the
65 POSIX style naming e.g. EINVAL etc. This package
66 also provides the standard strerror() function to
67 convert error codes to textual representation, as
68 well as an implementation of the errno idiom."

91 variable, rather than global."

100 Trace verbosity level for debugging the errno
101 retrieval mechanism in errno.cxx. Increase this

138 This option modifies the set of compiler flags for

140 to the set of global flags."
