1.Q: Is it possible to build the asn1c compiler on Win32?
1.A:
	At this point, the asn1c source code is tied to GCC-specific
	extensions in several key places. The CYGWIN environment with
	gcc compiler may be what are you looking for.

	Please also consider using the Online ASN.1 compiler at
		http://lionet.info/asn1c
	which generates platform-independent code.


2.Q: How to build a simplest BER (XER) encoder or decoder?
2.A:
	Please check the "Quick Start Guide" on ./doc/asn1c-quick.pdf
	Please check the "Examples" section of ./doc/asn1c-usage.pdf

	Also, try the following to build the X.509v3 parser:

		cd ./samples/sample.source.PKIX1
		make
		./x509dump -h


3.Q: Your compiler supplies a der_encode() procedure. How do I encode BER?
3.A:
	The DER (and CER) are stricter subsets of a more generic BER encoding
	method. If you encode data with DER or CER, all BER-conformant decoders
	will easily understand that. Hence, to encode data in the BER format,
	simply use the DER encoder, der_encode().

	See also:	ISO/IEC 8825-1 / X.690:
			"ASN.1 encoding rules: Specification of
			 Basic Encoding Rules (BER),
			 Canonical Encoding Rules (CER) and
			 Distinguished Encoding Rules (DER)"
