Subject: Prevent optimizing the pow() function
|
||||
|
||||
With the current GCC 8.2.0 from Debian, a section of code calling pow() in
|
||||
zzjson_parse.c is turned into a sequence calling exp(). Since no exp()
|
||||
implementation is available in syslinux those optimizations need to be
|
||||
disabled.
