Enables the compilation of C90 source code.
It enforces C only, and C++ syntax is not accepted.
This option can also be combined with other source language command-line options. For
example, armcc --c90 --gnu.
To ensure conformance with ISO/IEC 9899:1990, the 1990 International Standard for C and
ISO/IEC 9899 AM1, the 1995 Normative Addendum 1, you must also use the
--strict option.
This option is implicitly selected for files having a suffix of .c,
.ac, or .tc.
If you are migrating from RVCT, be aware that filename extensions .ac and .tc are deprecated in ARM Compiler 4.1 and later.
