Fix Build if WINAPI_FAMILY_PARTITION is undefined
I got this error when compiling:
builds/windows/ftsystem.c:201:29: error: missing binary operator before token "("
201 | !WINAPI_FAMILY_PARTITION( WINAPI_PARTITION_DESKTOP )
| ^
It seems that the preprocessor does not like to see such use of an undefined macro.
Tested with GCC-9.3.0
Attached patch fixes the issue by simply splitting the #if
statement into two lines.
