I tried it only for egcs-1.1.2 with "-g -O2"
Without -D__NO_STRING_INLINES time was 2m58s with -D__NO_STRING_INLINES
it was 2m48s, so it seems is one of the reasons it runs slower.
Now, can you please explain me a bit why does glibc2 use those inline
functions (if they are better why?), and what is the impact on compiling
software with -D__NO_STRING_INLINES defined?
Thanks,
