Subject: libserialport_internal: use new macro to enable timeradd, etc.
X-Git-Tag: libserialport-0.1.1~8
X-Git-Url: https://sigrok.org/gitaction?a=commitdiff_plain;h=4d8195fe3f8b5d2a206b8c1c1edeb4e3e0208ccb;p=libserialport.git

libserialport_internal: use new macro to enable timeradd, etc.

Since glibc 2.20, the usage of _BSD_SOURCE is deprecated. Fix it like
described here:

https://sourceware.org/glibc/wiki/Release/2.20#Deprecation_of__BSD_SOURCE_and__SVID_SOURCE_feature_macros

This fixes bug #716.
