Subject: sr/srd: SR_API/SRD_API/etc. is a no-op on MinGW.
X-Git-Tag: libsigrok-0.1.0~1
X-Git-Url: http://sigrok.org/gitweb/?a=commitdiff_plain;h=69e70c233ef6186131369ad596a96a2632bdcf85;p=libsigrok.git

sr/srd: SR_API/SRD_API/etc. is a no-op on MinGW.

This avoids warnings on a MinGW build. The feature depends on ELF files,
but MinGW/Windows uses PE files.
