PAC_PROG_CC

Find a working C compiler

Synopsis

PAC_PROG_CC

Output Effect

Sets the variable CC if it is not already set

Notes

Unlike AC_PROG_CC, this does not prefer gcc and does not set CFLAGS. It does check that the compiler can compile a simple C program. It also sets the variable GCC to yes if the compiler is gcc. It does not yet check for some special options needed in particular for parallel computers, such as -Tcray-t3e, or special options to get full ANSI/ISO C, such as -Aa for HP.
