Postfix 2.2.7 Compile on Solaris 2.8 ERROR

[freshrider]

Trying to compile postfix 2.2.7 from source on Solaris 2.8 SPARC with gcc compiler and getting the following error:

I saw one thread mentioning to set CFLAGS=-DSOLARIS=20800 but still nothing. Not sure if we need to patch stdlib.h, couldn't find a patch related to this case. I've tried older gcc compiler as well 2.95 with same result...I've also tried without including any SASL/TLS/MYSQL and it gives the same result.

Just wondering if anyone else has seen this and if they have a workaround?
