[Qt-interest] Linking C programs with qmake

[Nikos Chantziaras]

I have a project that consists of only *.c files.  Right now, I specify 
this in my *.pro file:

   QMAKE_LINK = $$QMAKE_LINK_C

This seems to work just fine, but I have to wonder whether this is 
actually the correct way to do this. Since all files have the *.c 
extension, shouldn't qmake figure out on its own that it should link 
them with QMAKE_LINK_C instead of QMAKE_LINK?  The former links using 
gcc here, and the latter with g++, which results in linking against 
libstdc++.
