Given the following .pc fragment:
includedir=/mingw64/include
Cflags: -I${includedir} -I${includedir}/taglib
Should includedir be assigned the value 'C:/Program\ Files/Git/mingw64/include', the expansion of ${includedir} will be chopped off after the first space:
Cflags: -IC:/Program\
With this patch, the expansion is corrected:
Cflags: -IC:/Program\ Files/Git/mingw64/include -IC:/Program\ Files/Git/mingw64/include/taglib
Create spaces-in-paths.pc
