When building blead with MinGW-w64-4.8.0 I see hundreds of lines like this come out from the Errno build:

Bareword found where operator expected at (eval 22) line 1, near "13834l"
        (Missing operator before l?)

This doesn't happen with MinGW-w64-4.7.4 or earlier, or MinGW, or VC++.

The change in behaviour is due to changes in the MinGW-w64 headers. E.g. 4.7.4 has:

#define ERROR_IPSEC_IKE_PROCESS_ERR_ID 13834L

but now 4.8.0 has:

#define ERROR_IPSEC_IKE_PROCESS_ERR_ID __MSABI_LONG(13834)
#define __MSABI_LONG(x)  x ## l

The lowercase "l" rather than uppercase "L" trips up Errno_pm.PL. The attached patch fixes this, and I think it should be a 5.20 blocker -- as the attached Errnos.tar.gz shows, the difference between the 4.7.4-generated Errno.pm and the original (i.e. current) 4.8.0-generated Errno.pm is HUGE. The fixed 4.8.0-generated Errno.pm is much more like it.
