Hi,

I've encoutered some problems when using libgcrypt from within C++ code. The
problem is located in libgpg-error in gpg-error.h. The functions gpg_err_code
and gpg_err_source have a return value of an enum type but they return an
integer. The compiler (gcc 3.2) complains:

gpg-error.h: In function `gpg_err_code_t gpg_err_code(unsigned int)':
gpg-error.h:464: invalid conversion from `unsigned int' to `gpg_err_code_t'

I think the problem is the different representation of enums in C and C++. The
problem could be solved by inserting en explicit cast to the enum type. For
example:

static __inline__ gpg_err_code_t
gpg_err_code (gpg_error_t err)
{
return (gpg_err_code_t)(err & GPG_ERR_CODE_MASK);
}

It would be great if one of the developers of libgpg-error could fix this,
because at the moment I've to modifiy the include file, which is not really a
good solution :-)

Best regards,
Ralf.
