The manual states (in (libc)ISO C):

  The GNU C Library is compatible with the C standard adopted by the
  American National Standards Institute (ANSI): ‘American National
  Standard X3.159-1989--"ANSI C"’ and later by the International
  Standardization Organization (ISO): ‘ISO/IEC 9899:1990, "Programming
  languages--C"’.  We here refer to the standard as ISO C since this is
  the more general standard in respect of ratification.  The header
  files and library facilities that make up the GNU C Library are a
  superset of those specified by the ISO C standard.

... so, probably any ANSI C (or better) compiler.
