Summary: sdcc won't compile frexpf.c and ldexpf.c for z80 processor

Initial Comment:
SDCC version: 
mcs51/gbz80/z80/avr/ds390/pic16/pic14/TININative/xa51/
ds400/hc80 2.5.0 #1020 <May 8 2005> <MINGW32>

First, I don't know why most of the functions in 
math.h are not compiled for z80 microprocessor.
Please let me know if you have any reason for lacking 
these functions.
Right now I am trying to compile these functions for 
my z80 project. Most of the math functions can be 
compiled with -mz80 option.
For example:
sdcc -c -mz80 sinf.c

However, file frexpf.c and ldexpf.c can not be 
compiled with the following error message:
frexpf.c:36: error 9: FATAL Compiler Internal Error 
in file 'gen.c' line number '6266' : Asked to shift 
right a long which should be a function call
Contact Author with source code
ldexpf.c:35: error 9: FATAL Compiler Internal Error 
in file 'gen.c' line number '6266' : Asked to shift 
right a long which should be a function call
Contact Author with source code
The command I used is
sdcc -c -mz80 frexpf.c
sdcc -c -mz80 ldexpf.c
I have attached the frexpf.c file with this report.
Please let me know if this can be solved or not.
Your help is appreciated.
