With gcc warnings turned up to "irritating" (-Wall -Wextra), there are a couple of build warnings in wolfSSL:

cyassl_int.c:171: warning: ‘inline’ is not at beginning of declaration
cyassl_int.c: In function ‘DoCertificateVerify’:
cyassl_int.c:4903: warning: comparison between signed and unsigned
ssl.c: In function ‘ProcessFile’:
ssl.c:663: warning: comparison between signed and unsigned
tls.c:242: warning: ‘inline’ is not at beginning of declaration

not really important, I just noticed because we build with -Werror.
