5442e9f9d8 * insert explicit type cast for the count parameter of move/fillchar wrapping C functions, 
avoids a warning in combination with -O3 and negative count values

daa746243a * use clib constant instead of literal 'c' in case we have a target where the library is not called 'c' (hopefully all targets that use cgeneric.inc have the clib constant declared in their sysos.inc)

dcfd734bbf Fix cycling with -dFPC_USE_LIBC on Linux systems to allow usage of FPC Linux programs on OSv. 
memchr seems to have a bug on recent Linux systems if the count that is passed in is larger than the buffer (in our specific case the count is -1 to find the 0 byte of \0 terminated strings): the function "randomly" fails to find the byte and returns zero thus leading to for example incorrect parameter handling.

rtl/inc/cgeneric.inc:
  * use rawmemchr on Linux if -1 is passed as count

4ebc34c5e7 * Promoted result type of FPC_PCHAR_LENGTH and FPC_PWIDECHAR_LENGTH to SizeInt.

22aacd2a60 * return 0 for length(pchar(0)), like Kylix does (using corrected and 
multi-platform version of patch in r12461, which caused the i386 version
    of fpc_pchar_length to return 0 in all cases, which used tabs, and did
    not include a test case)

6121df1f67 * moved inclusion of sysos.inc higher up in system.inc, so that 
cgeneric.inc can use the C types
  * imports of C routines in cgeneric.inc now use C types

e8322a83e4 * optimized generic implementations to use pointers instead of 
array accesses. This also allows better register variable
    optimizations

0f26252376 + cgenmath with libc math functions. Faster than the routines in genmath 
and also have full double support (exp() only has support for values in
    the single range in genmath, for example). Used in FPC_USE_LIBC is
    defined
  * several fixes to allow compilation with -dHASINLINE, but internalerrors
    because of missing support for inlining assembler code

5439babeb5 + cgeneric.inc: implementations of rtl routines based on libc 
* system.inc: include cgeneric.inc before powerpc.inc/i386.inc/... if
    FPC_USE_LIBC is defined
  * powerpc.inc, i386.inc: check whether the routines they implement aren't
    implemented yet in another include file (cgeneric.inc)
