Almost - the bug is in textfmt it fclose()'s twice.

Its because the other libc's have static array of FILE structs allocated
when the program starts that don't get deleted till its finished. glibc2
allocates FILE structs as needed.

Small sample prog:
	FILE* f1, f2;
	f1 = fopen("file1.txt", "r");
	fclose(f1);
	f2 = fopen("file2.txt", "r");
	fclose(f1);

Under glibc2 this segfaults, under the other libc's(ie Sun OS) you just
close f2!!!

There is a small patch for this at: http://www.trump.net.au/~rjc/hylafax/
