Re: [Sdcc-user] Another compiler glitch: Is 'data' a pre-definedkeyword?

[Jan W. <we...@ef...>]

This is a well-documented feature, see e.g.: http://sdcc.sourceforge.net/doc/sdccman.html/node182.html

"Certain words that are valid identifiers in the standard may be reserved words in SDCC unless the --std-c89 or --std-c99 command line options are used. These may include (depending on the selected processor): [...] 'data' [...]. Compliant equivalents of these keywords are always available in a form that begin with two underscores, f.e. '__data' instead of 'data'."
