#32 Build fails under certain compilers

[Nigel Hathaway]

I am compiling under gcc 4.4.7, and the build aborts with the following errors:

In file included from crypto/cmp/cmp_asn.c:72:

However, gcc 4.6.3 seems to tolerate this (that's the one with Ubuntu 12.04)

[David von Oheimb]

Good point. I had not seen this before but have been able to reproduce this with gcc (SUSE Linux) 4.8.5 with the -pendantic option.
The redundant typedefs were due to forward declarations for these structure types in cmp.h - this is going to be fixed soon.

Fixed in GIT revision c73ae5df0a - now commited to the CMP branch.

Thanks for reporting.
