I'm having a trouble in compiling and liking a program listed as
follows.

#include <stdio.h>
#include <math.h>

main()
{
  double l;
  l = lgamma(1);
  printf("%lf\n", l);
}

Compiling environment is on Win NT 4.0 with cygwin32 beta 18.

Compiling processes and messages are as follows:

bash$ gcc -o lgamma lgamma.c
/tmp\cc0015931.o(.text+0x1b):lgamma.c: undefined reference to `lgamma'
gcc: Internal compiler error: program ld got fatal signal 1

bash$ gcc -o lgamma lgamma.c -lm
C:\gnuwin32\b18\H-i386-cygwin32\lib\gcc-lib\i386-cygwin32\cygnus-2.7.2-970404\../../../../i386-cygwin32\lib/libm.a(w_lgamma.o)(.text+0x7):w_lgamma.c:
undefined reference to `signgam'
gcc: Internal compiler error: program ld got fatal signal 1

Please give me solutions against the error.

Thanks
